I have a 04 ls that has been with a mechanic who gives up. The car idles fine but has no power or acceleration all COP's have been changed. Also the computer is not throwing any codes. Mechanic says that cylinder 3,2,1 have sever mis fire and are pretty much dead but dose not know why.

View 3 Replies I was driving my Taurus a few days ago when it lost all acceleration and power steering. The engine seemed to be running okay, and it restarted at the side of the road, but still no acceleration. I called AAA and had it towed to my mechanic. The following day they called and could find no problem.....
they had driven it several times, checked out likely causes but found nothing. This garage has been very reliable in the past. They said it could just be an electrical issue that may or may not happen again. The car seemed fine when I was driving it today, but I am worried about it happening again. What could have caused this/what I should do?
Just recently my Prius Taxi with 340,000+Km has developed a little problem,it starts fine but after 20-30 seconds it begins to feel like it's not running properly on all four cylinders,if i go to the exhaust pipe it seems like it's spluttering slightly.
Yesterday I changed the plugs,checked air filter and all connections,everything fine, when I accelerate it feels hesitant but after the car gets up to temp it seems to go away,it only happens when i start it first thing or if it's been left for a few hours, it's never had the throttle body cleaned and I'm wondering if what I'm describing is a symptom of this?
I have a 2002 Nissan Quest. It starts fine, idles great. But, when I try to accelerate, the car bogs, hesitates, misfires and I get p0300 random misfire, p0325 knock sensor. I get no dtc when it is just idling. The fuel pressure is fine, regulator works good, the cam sensor is clean, the coil tests good, the compression is good, as are the wires, cap and rotor.

View 5 Replies2007 5.4 . Starts good , idles all day. As soon as you try to rev it, it stumbles rattles etc. Shut it off, wait a second, restart then Idles fine. I watched live Data and it carries on when the VVT solenoids become active (above 800 rpm).There duty cycle goes to 60-70 percent while revving. I think it Is just one side of the engine. Could be VVT solenoids sticking on? yes ? No?
View 3 Replies2000 F350. Starts great. Idles fine. After it warms up a little, it will run rough and lose power like it is only hitting on a few cylinders. It will eventually stall unless I push the clutch in and bring it back to idle and then it smooths back out. I figured it was starving for fuel but I can rev it with the clutch in with no issue. I ran it up to 2500 rpm and held it there with the clutch in and ran perfect.
I let the clutch out and start rolling....missing again. The check engine light does come on but my scanner says that there are no codes stored. If I idle it, it will smooth out, and the light goes off. All I have done so far was change the fuel filter which was almost plugged shut and the housing was full of rust looking debris which I cleaned out. BINGO! Nope. Same issue.
I am really at a loss as to where to start. I bought this with 120k on it and it now has 170k and I have not had to do anything other than routine maintenance.
I have a 99 jimmy replaced rotary button, cap, plugs, wires. The truck doesn't seem to run right. It idles fine but when in load it starts to sputter a bit. Going down the road between 2000 and 2500 rpms the tach jumps a bit. Now if I put it to the floor the truck runs out fine.
View 3 RepliesI used a OBD scan tool and all it told me was my idle air control system rpm is lower than expected and my evaporative system has a high purge flow. What this means, can I fix it or do I have to send it to a shop. Also when idling the short term fuel trim 1 is at -3% whatever that means.
View 16 RepliesI'm having a bit of trouble with my fathers '03 Ranger Edge 4.0L. It has about 100k miles on it, and we keep it very well maintained. This is the first major problem we've had with it.
When the problem first occured, it had been driven about 30 miles on the highway and about 5 miles after getting off the highway, he pulled up to an intersection and stopped. As he started accelerating again, it all of a sudden started sputtering, surging (almost exactly as if it were running out of gas), and then stalled. It continues to exhibit this behavior. It will start and idle fine, but struggle and then stall when given any amount of throttle. It's also an automatic transmission if that makes any difference.
Fast forward to this past week after we had it towed home. We have checked the fuel pressure, and its dead on at about 64psi. We changed the fuel filter, changed the PCV valve, changed the upstream O2 sensor, put in a new air filter, cleaned the MAF sensor, and cleaned the intake of the throttle body. We're now at a loss as to what could be causing the problem. The CEL is not on, and there are no codes being shown when we plugged it in. We also thought it may have been bad gas, so we drained the tank and put fresh gas in from our preferred station. The plugs and wires are also fairly new, only about 4k miles on them.
Are we missing anything here? What else we could try? The absolute last resort is taking it to a shop, we're going through a rough patch with finances.
My 03 Corolla S - 5 Speed has developed a sound while driving, only when giving it gas. The sound goes away when I press in the clutch. It doesn't make any unusual sounds while parked and idling.
The sound, sounds like a knocking noise. At least to me that's what it sounds like. My car has 156k miles on it.
The car idles fine, rpm's are good on while driving, temps good and still gets really good gas mileage.
Does it have something to do with my clutch, since the noise goes away when I take my foot off the gas, or press the clutch in?
Is there something I should be checking? All my fluids are good, brake/clutch, oil, transmission fluid, radiator, etc.
The car idles rough on cold mornings but runs fine. It will stall while idling but starts back easily. I am getting a 1131 and a 1151 code with my scanner along with 0300 and lean bank 1 codes. I started having these problems after I had to remove the upper intake to replace coil packs. I was getting egr code and had an egr port completely block off but cleaned that out and no longer get the egr codes. Spraying carb cleaner around the engine I get a very slight bump in rpm around a couple of the intake ports could that be my problem or should I look deeper?
View 5 RepliesI'm trying to get my neice car going. .I went to move her car yesterday after a snowstorm and it idled fine but would bog down when I pressed on the accelerator. While it was running I checked to see if the air filter was dirty, it was and as soon as I pulled the snorkel off the car stalled. I put everything back in place and after running for a half hour it seemed fine. She drove to school but before she got there it started to bog down again so she pulled into a Toyota dealer. Later they changed spark plugs, new air filter and cleaned MAF sensor. Worked better until the next day, now it will crank over but will not even make an attempt to start. I tried to clean the sensor with rubbing alcohol but no luck.
View 3 RepliesAs the title says, I just replaced my JVC harness and glow plugs, now it start and run fine, but it will suddenly raise the idle to 1000rpm, and sit steadily untill I press the gas pedal, then it will fall into its normal idle range. I replaced the stuff today, and I did not get the time to get the engine hot, or test drive it, before I had to leave. But the engine did start fine, and idle fine. Except from the sudden raise after a few minutes idling, it will then hold around 1k rpm.
Strange, can't remember if it did that before. I get no fault codes on my SCT device. The car has been sitting for 3 months before I finally got the glowplug relay, mine was non functional.
Today I acquired a 1982 F150 with a 302 engine, 4 brl. Edelbrock carb. The truck starts and idles just fine, but when I come to a stop, try to give it gas to go it dies. It starts right back up, and I have to rev it high a couple of times then put it in gear and it will finally go. When I got it home I let it idle a few minutes and tried playing with the air and fuel mix but don't know what I'm doing, really. It seems I can hear a hiss, and when I was reaching for the air/fuel screws I got a little shock on the hand from the distributor. We want to use this truck as a farm truck, and plan to get a manual for it, but what might I might check for the cause of it stalling.

My car was running fine, then one day it started sputtering while driving, mostly when I accelerated. It stalled and I could not get it started. This happened on a day when it was raining hard, but not sure that had anything to do with it. A few days later when I went to pick the car up it started right up, it had stopped raining and been dry for 2 days prior. But about a mile into the drive back home it stalled and I could not get it started.
Here is what I have tested so far.
- Put in new fuel filter.
- Tested the fuel pressure and pressure regulator
- Tested the injectors with a noid light.
- Tested that the spark plugs were producing a spark.
After I pulled the plugs and cleaned and dried them (they were wet with gas) the car started, but I think not because of anything really related to the plugs. What I've noticed is that when cranking the engine if I give it gas it will not start but if I keep off the throttle it will reluctantly start. But once it starts the idle is smooth and as it should be. Then if I give it any gas it immediately stalls. It seems to me given these symptoms that it is getting enough air to idle but not enough air to match the increased gas.
The only CEL code that I'm getting (which I had before this issue occurred) is the "closed throttle position switch" (I forget the number). If it was an MAF, or IAC, or EGR issue would I not get a code? What this could be and how to test it. Again my guess is its an air intake issue but not sure where.
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
So my "farm truck" is idling very rough, to the point that sometimes that it stalls out. At high idle it runs fine but when its at a idle its very rough. Its been running fine until probably a month ago or so and its just getting worse. What it could be? I am thinking it might be that something is dirty but i just dont know where to start with figuring out what the problem is.
View 9 RepliesI have a 01 f-150, 4.6L, with 160k miles on it. Symptoms: It idles fine with an occasional surge. It sputters in all gears like a misfire (all plugs and COPS replaced 2 months ago). Sometimes it stalls out going down highway or as I turn in my driveway. It also seems like its slipping a little without the "hard jerking into gear". Occasionally the rpm meter will peg low and then return to normal.
The only code that I received was P1451. I changed the canister vent solenoid but the symptoms remain. I've checked voltage on the TPS (the variable voltage checked out but I didn't get the 5V ref. voltage). I've cleaned the MAF sensor. I've also changed the fuel filter. I've resistance checked the connector to the PCM and found several pins that are at ground. I'm not sure what to do next.
I have a 2002 F150 super cab with the 5.4 liter v8. I hit a large water puddle on my way to work Tuesday. I was going faster than I probably should have been. After hitting the puddle the truck lost power. It idles fine but as soon as I put it in gear it sputters and has no power. Also, the O/D drive light is now flashing. What might be going on with it.
