Fort - ZX2 :: 1998 - Hard To Start And Runs Rough Through First Acceleration
May 21, 2014
I'm having a weird issue with my 1998 Ford ZX2. The car is very hard to start when cold and it runs extremely rough, but only through my first acceleration under load. In other words, I can rev the engine a few times while in neutral, and it will run very rough, and once I start driving, it runs really rough through my first acceleration, but then it smooths out and runs fine from then on until I stop it and let it call off for 30 minutes or more. If I restart it within 30 minutes or so, everything is fine, but any longer that that and the problem reappears.

My '03 6.0 is hard to start and runs rough when cold. Not just cold outside temps, but engine not up to temp. Starts and runs like a champ once it's up to temp. It was doing this when I got it, but it's getting worse.
From what I've read the common culprits are:
1 - failed solder joints on FICM power supply board
2 - bad power supply side of the FICM
3 - updated flash needed for FICM
4 - injector stiction
5 - leaky O-rings at high pressure oil rail to injectors
I have read up on how to run the voltage test on the FICM with a multimeter.
Seems like I would have to go to a dealer to have the software version for the FICM checked.
I am 100% competent to do the tests and/or repairs myself, but since I recently moved in with my fiance in a condo and my tools are in storage, I will have to do it at a friend's house. That being the case, I want to know what all of the common things are that I may need to check for so I am prepared. So, I wanted to see if there were any other common causes of this issue.
I plan to test the FICM voltage and give FICMRepair.com some business if that's the problem. And if that's not the problem (or maybe even if it is) I will get the injector seal kits and replace all of the injector seals as well as disassembling and cleaning the spool valves in the solenoids. I will also change oil and fuel filters with Motorcraft parts and Rotella synthetic oil while I'm in there.

I have an 03 F350 with the 6.0L. It has 210,000 miles on it and the injectors are beginning to be suspect. Its very hard to start when its cold, smokes and runs like crap untill it warms up.
I've found a set of injectors out of a 2005 truck with 8000 miles on them. The truck was overboosted and blew a head gasket.
Now finally to my question.....Can the overboost damage the injector? Would it be safe to buy these and install them or rebuild them before install or just leave them alone?

2001 Ranger Edge 3.0. Like the title says, when I start my ranger it idles really rough. If I give it gas it shudders like it's gonna die. After about 2-3 minutes it smooths out. If I'm on the interstate and down shift to pass someone, while accelerating it feels like I have a misfire (no CEL given) not all the time though. I've changed plugs and wires and it stopped doing it so I thought I had it but, it continued a few days later. Then I changed the fuel filter and it stopped again for a few days. Well it's back again. I'm thinking it's the fuel pump but I wanted to check here before I take my truck bed off. I also checked for vac leaks and I'm all good there.

THE FREQUENCY: This is a condition that has become progressively worse over the last six months. Initially it occurred once a week and now it is happening almost every day, lasts longer and is more acute.
THE SYMPTOMS: Initially and randomly, while driving at any speed, the car would begin to hesitate as if it might stall but did not- The hesitation was much like a shudder or power loss. At this time the check engine light would blink and stay on for a couple of days. This whole event would last less than a minute and the car would return to normal until the next one.
Now, six months later, it is occurring almost every day. At startup, at low speeds, at stop lights.... A LOT!
WHAT HAS BEEN DONE SO FAR: After frequent and unsuccessful visits to the Volvo Dealer all the plugs, the wires, the cap, and the rotor have been replaced with no luck.
The dealer says the code indicates a misfire on the #3 cylinder.

My 98 Maxima won't idle without dying, it sputters when you accelerate, and it tries to die while coasting. I've changed two O2 sensors (AutoZone gave me the code for bank 1 sensor 1 & 2) changed spark plugs, tried fuel injector cleaner, oil change, and cleaned MAF sensor & checked the wiring. It;s still spitting out the black exhaust. Although after changing the O2 sensors it quit for about a day or two but started again (I'm guessing the other sensors need to be changed to) But the main problem is once it warms up, it really runs like crap, and is a major gas hog. I'm getting about 12 Mpg.

Starts good cold and hot. Taking off like a grandpa on an evening drive don't notice a thing. Only codes that keep coming up are 2614 and 2617 which are cmp and ckp open curcuit codes and a software incompatibility code for FICM which is due to the updated software in the fresh FICM I installed. HPO pressures are good, has boost, idles smooth, revs nice when in park. New injectors (cause it was running rough especially cold before) and CMP and CKP (because of the above codes and didn't change)and ICP and IPR (last 2 installed because of HPO codes that are gone now with the IPR and ICP). Fuel pressure is 65psi (updated spring). When you step on it while driving it sputters and bucks like it's out of fuel, let off the throttle a bit and it purrs like a kitten. I'm a little stumped. I think it puffs a little white/blue smoke while it bucks.. not much tho. and it comes in little puffs. Took off filler cap and there is almost no blow by.

1998 Jeep Cherokee sport ... My mechanic tells me that my #1 fuel injector is always spraying and that that is why the jeep runs rough. This is after he already told me that my injectors were clogged and needed to be replaced (which he did). When the car is idling for a while, the exhaust really begins to smell like gas, so this seems to make some sense to me, unlike his previous diagnosis. But now he is telling me that I need to replace the computer to fix this problem.

My F150 with 175,000 miles on gave me a the ol' P0305 code indicating misfiring in cylinder #5. I changed the plugs and wires using Motorcraft wires and Motorcraft AGS34FM plugs.
Now the truck idles fine, does not give a OBD code but runs rough at 2,000-2,500 rpm. Tried it out on the highway and it started "bucking" a bit. Not sure what to try next.

My 99 250, 7.3 is having some strange issues as of lately. When I start it in the morning, when the engine has fully cooled down, it starts right up, then it throws the "wait to start light" runs real rough and just shuts off. Run the glow plugs a few times, start it up and it will do the same thing for maximum 30 minutes, then all the sudden I start it and it runs fine. I've replaced the fuel pump, cleaned the fuel bowl, new fuel filter, I just don't know where my problem could be. It doesn't make sense. But once I get it running and it warms up, runs fine all day. Go to bed, wake up, has problems again.

1995 G20 5.7L... This van runs great when first started and continues to run fine after it's warmed up and will do so until it’s turned off and restarted. When first started vacuum at idle is steady at 21” and 10” at 55mph cruising speed. I can continue driving for an hour or so and it will continue to run fine. It's only when I shut it down and restart after 20 minutes or so that I have a rough running condition. After parking for 10 to 20 minutes and restarting idle is still steady at 21” vacuum but the van hesitates on acceleration and runs rough at cruise with a 5” vacuum. If I continue to drive I get low vacuum trouble codes for the MAP and Oxygen sensors. I’ve replaced the oxygen sensor and performed a diagnostic on the MAP sensor which checks out ok. I’ve checked for vacuum leaks – none found. I've replaced the spark plugs, cap and rotor. What to look at next?

I'm working on my sons 1985 Celica GT 22RE. He was having problems with it running rough.
I've isolated it down to the number 1 cylinder being starved on warm starts. If you cold start it the problem does not occur but if you let it sit warm for 15 minutes it will fire up but nothing from number one cylinder. Lots of spark but no firing. So I'm going to tear down the EFI and move the injector to see if the problem follows it. Will probably see if I'm getting any voltage to the injector while rough before tearing down.
I can't find anything about an injector not working once warm so I'm thinking it may be an ECU problem.

I bought a '99 MX-5 in the fall with 100000 miles on it. Most of the time it runs fine. But about every two weeks when I go to start it it will run real rough like its only hitting on three cylinders then will eventually smooth out after anywhere from 5 seconds to 2 minutes. But today it wouldn't start at all. Finally started just fine after trying for 15 min. My mechanic changed the EGR valve but it hasn't worked. The check engine lite stays on all the time but when it starts rough the lite will flash.

96 civic 120K miles, stock, automatic.
In March I was running low on fuel, maybe 1 gallon left in the tank. It took a few cranks and on the last try i gave it a little gas and it started, albeit very rocky for about 1 minute of driving, filled up immediately and 2 freeway miles later, no real issues. I live in LA so very low ambient temperature is not a problem.
April through May, starting was a little rocky, it was inconsistently rocky too, sometimes there was no problem. Usually it's weak, stuttering, sometimes just cranking but I seem to get it to start. I stopped giving the pedal gas because I read that's bad (I own a vintage bike, so it's news to me). I don't drive that far and figured I'd try some Seafoam and some freeway miles would clean out any debris. Worked for that tank a bit for the next tank before the problem came back.
Still getting the rough starts, but now when I give the car gas as I pull out sometimes it doesn't accelerate for 15-30 seconds, maybe 25 yards then it drive like normal. No dying at all but getting worse with starting up.
I've tried turning the key (not turning the engine over) 5 times and cranking on the 6th and it seems to work. I thought maybe it's the fuel pump or fuel filter but read it could be an ignition coil/ spark plug/ spark plug wire issue. Two different ball games.
My MPG is not really droppingI had a new fuel filter put in in February as routine maintenance (thing was on so tight had to bring it to a shop so no rookie mistakes there). Timing belt &water pump replaced 6,000 miles ago

2004 Malibu 3.5 v6. 101,000 miles. In order to get engine running gas pedal has to be pushed all the way down to get it started. Engine will not start by turning key. Car initially starts sputters and then dies. Pedal to the floor while cranking engine fires and runs. Which direction do I go first at. Ignition or Fuel. What should the fuel pressure be with key on engine not running ?
What should pressure be at while running ?
What is the time frame pressure should hold at and for how long ?
Ignition, Coil,Wires,Plugs. Are these the only ignition parts to look at?
Check engine light is on but has leak in exhaust. Exhaust needs to be welded. All parts above are original. Neither Fuel Pump nor Ignition Component have not been changed. Which do I do first ?

I am working with a friend on his 99 Ranger with a 4.0 . When first started it will idle rough and hesitate for the first 300 feet or so, and then clear up and run smooth the rest of the day. If he lets it set for 6 or more hours it will repeat the problem. He has taken it to a local Ford dealer and they have replaced spark plugs, plug wires, coil pack, cleaned the throttle body, checked the air idle motor and passage.
He has had it to the dealer 3 times and their latest plan is to pull the heads @ a cost of 1500.00 to start. Since it runs well, no coolant in oil or oil in coolant nor loss of either fluid, I couldn't figure why they want to pull the heads.
To date it has not thrown a code, I ran it on a New Generation Star tester and cannot find a code. The truck runs great after the first intial start up and does not give any signs of cutting out or lack of power. My guess is it is losing fuel pressure overnight and is taking a while to reprime. Original fuel pump and 160K miles. Will do a fuel pressure test this weekend.

I have a 1999 Ford Escort SE wagon with 112k miles on it. Last week when leaving work my car started very rough. This was unusual so I killed and restarted the car about three times before letting it run it's course (~30 seconds), after which the car ran fine. About a week later on my way to work the car seemed to 'sputter' (for lack of a better word) when I pushed down on the petal looking for some power on two separate occasions. On each side of the sputters the car seemed to respond fine, but when it did sputter there was a severe lack of power. I got to and from work just fine, but while letting the car idle in the parking spot of my apartment for a minute before shutting off the engine the check engine light finally came on. The following morning the car again started rough (as if it were misfiring/running on 3 of 4 cylinders) and this time it took a good minute before smoothing out. However, after the car smoothed out I experienced no issues on the way to work, no sputtering, no loss of power, nothing. Doing some initial online research I feel that the problem may be one (or more) of the following:
-Fuel pump
-Vacuum lines
-O2 Sensor
-Spark plugs (they are original)
-Fuel Filter (it is actually past due for replacement)
I plan on getting this checked out ASAP, but that still may be 2ish weeks away with my schedule. Some similar reports say that I may be having a 'lean mixture' issue (not getting enough fuel), but I haven't had the time to check the code. My question is, how "safe" is it to continue driving my car with the current situation? Is it at a super high risk of failure/random stalling during rush hour? Will it cause any damage to the engine if there is a cylinder misfire upon start up? I was also wondering if the car would be reasonably reliable to drive on a ~400 mile road trip on an upcoming weekend, but I am making plans as if it is not.
Additional Details:-Tried charging the fuel lines (car to 'ON' then 'OFF' position 3-4 times), had no effect on the morning start-up-Commute to/from work is about 20 miles

About 2 weeks ago my 1997 Buick Park Ave (115,000 miles) began running bad during a heavy rain storm. It was running fine. Then all of a sudden at a stop light the motor hesitated and wanted to stall. I nursed the gas peddle and limped home and turned the car off. The car hesitated and sputtered all the way home as if I was running out of gas.The next day the car would not start. It turned over but would not start. I tried starting the car for three days. My mechanic friend later diagnosed the car and stated the computer was not functioning correctly. He replaced the computer. The new computer seemed to correct the problem.
The car ran great for the next 2 weeks. Yesterday, it was raining hard while I drove the car about 150 miles without any problem. Then suddenly again the motor started running badly. Again, the motor wanted to stall and hesitate as if I was running out of gas. I limped home again. This morning I tried to start the car without any luck. In addition to installing a new computer, In the last 2 months I have changed all the fuel injectors and installed new spark plugs.I have also changed the fuel pump and repaired the fuel tank. My mechanic say the cam sensor and crank sensor are operating correctly. There is spark coming from the coil packs and to the spark plugs. I do not want to randomly change parts.

I got 2000 tdi with 270000km on it and have a few issues with it and am looking for some information before i start doing some work to it.
First problem excessive blue smoke on start up also runs ruff tell it warms up.
Second the is a screeching noise on start up some times. happens most of the time when the car is cold.
Third sounds like something is dragging or rattling but i have checked and there is i can see.
Fourth when the clutch is in and the brake is on the car runs ruff at idle. i think it has something to do with vacuum used for the brake booster but not sure.

I have a 2000 E350 boxtruck with a 5.4 auto. The motor is a new rebuilt with about 4000 mile, coils were replaced with motor, injectors were rebuilt with motor.Today (500 miles from home) the truck died. I was going up a slight hill on an interstate. It will still start, but runs very rough and when I put it in gear and step on the gas it dies.
So I had it towed to a garage. While pushing it into the garage I noticed my gas cap was missing. I know it was on 45 min earlier because I got gas. Did I forget to put in back on? probably.. But I wondering if the missing gas cap could cause the truck to run bad,vary bad?
