Almost everytime I drive the car for more than 2 consecutive it acts as if it drops a cylinder..running rough. The next day it will run fine until 2 hours go by...and so on. I have changed plugs wires and coil pack.... 4 cylinder .. automatic

View 1 RepliesI was driving the car yesterday and was getting on the highway ramp and stepped on the gas and car went crazy. It started to accelerate and decelerate by itself. I had no control of the car whatsoever. When driving at 0 to 40mph no problem so far, but anything over this car will jerk, like it's changing gears by itself, 'going fast and slow.'What is this? Do I need a fuel filter, or plugs or what? I don't know when the last time I changed anything the car mileage is 135,000
View 1 RepliesI 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
I have Warn hubs that I have to lock in. All works good. A/C goes to defrost at first when cranking but then runs fine after a couple seconds. So, I was thinking that maybe my pump is running all the time. Who knows. I'm sure all my vacuum lines are dry rotted. What exactly is the need for it exactly and what's the best way to cap? Hoping to do it at the unit itself if possible.
View 6 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.
My 1999 Jeep Cherokee, 4L inline 6, has a very weird problem. Usually, after starting, it runs well for around 10 seconds, during which time I back up and get ready to leave. Then when I switch to drive, it starts to run poorly, having no acceleration in speed or and very little in engine rpm, until I stop using the brakes. Exactly when the suspension relaxes, the idle returns to normal and it runs perfectly after that.
Sometimes the rough running starts while I'm backing up too. So I don't think it related to the transmission. But all I have to do is completely stop, and then it runs great from then on.
This doesn't happen every time, but probably 60-80% of the time. It's been happening for about 2 months now.
Let me start with I have a 2003 f250 5.4. The motor blew on my truck and I had a 100k motor dropped in it. I've put new spark plugs, ohmd out the coils. I tried both sets of injectors. cat delete and new fuel pump. It has rough idle and stalls but runs fine at higher rpms. Also has basically no brakes. I am thinking vacuum but I've check all the lines. No codes either!! also cleaned throttle body.

I've only driven the car for about 2 months, Ive never had an issue with it until yesterday other than an occasional hard shift when driving the car hard. Yesterday when I dropped the car in drive it wouldn't pull at all, I sat in my apartments parking lot continually revving the car high in drive but it wont do anything, its like the car is in neutral. Reverse works and I can drive by manually shifting from first to second and then putting the car in drive, but if I put it into drive before reaching 3rd gear it jumps back to neutral.
I checked the linkage, and the lever it connects to on the transmission; when put into drive the position of the lever coincides with the neutral position. I called a few local transmission shops and they diagnosed is as a broken sprag, but from reading online it seems like it could be a clogged transmission filter or a faulty transmission range sensor. Prior to this issue I would sometimes here a whistle coming from under the hood when driving, I didn't know until today that a whistle is indicative of a vacuum leak, but wouldn't it throw on my check engine light? I have checked my transmission fluid, its at the correct level and is a nice cherry red, it doesn't have any bad or burnt odor.
1993 Dodge Ram 2500 .... Multiple symptoms... some times engine turns over but truck will not start. sometimes engine dies whether driving at slow or high speeds. Happens whether engine is cold or warm. After sitting a while, the truck starts and will run for several days. Has 40 lbs of fuel pressure, we've changed out the ignition switch, crank sensor, distributor cap, rotor, pickup, engine control module, crank shaft position sensor.This has been happening for three months, I've been towed in 4 times. When mechanic connects diagnostic tool to the ecm, the engine starts and runs fine. Diagnostic shows no data of previous problem.
View 3 RepliesI have a 1999 ford escort 4 door sedan, when the car is cold I can get it to start and it will run just fine, after it starts to warm up, it starts to make a misfire/ sputtering noise when it is starting to die when idling. when I am driving it, there are no signs it is going to die.
I took it to the ford dealership today and they said that I need to replace the fuel pump, and the relay control module.
I just replaced the fuel pump a week ago because I thought that was the problem. So I am thinking it is the Relay Control Module- only problem is I don't know where it is located, where it is?
This problem has been getting worse over the last 2 years. When the car starts it idles fine at about 1000 RPM. As soon as it warms up, it starts to idle rough, between 500 and 750 RPM. It almost quits running. As soon as you give the car some gas it runs just fine. About 3 weeks ago I got a "Engine Lean" check engine light error. I reset the system and have not gotten the error again. Since then I have: changed the MAF cleaned the EGR (made sure it closes completely and ohm out the coils in the actuator) changed the O2 meter on the exhaust manifold cleaned out the throttle body Ohmed out the air idle controller. What I should check next. I was planning to check the fuel pressure in case it is a fuel system problem. It is a 1999 ....
View 5 RepliesI start the car - a 2001 Ford Focus 4 cyl DOHC. It runs fine for 30 seconds then stops, as if it is no longer getting fuel. I can't start it again for a couple days then the same thing happens over again. FWIW, I parked the car for 8 months before this happened and only started it once in that time. But it ran fine then and before I parked it. What can this be?
View 1 RepliesMostly occurs at high speeds and climbing hills. Could it be a transmission problem? Or a fuel pump?
View 2 RepliesThe check engine light came on again after coming on about a week ago and then shutting of by itself. Everything seems to run normal with the car so I don't know if I should ignore the light and just keep driving or what. What would you do? My car is a 2011 Ford Taurus.
View 1 Replies2010 Escape with 74,000 miles. Backstory: This is my daughters car who is away at college about 300 miles away. About a year ago the engine started hesitating when driving and would stall to idle at highway speeds. She took the car in to dealer and they replaced the Throttle body under the CSP that had been issued just prior to the dealer visit. All was fine for about 3 months, then she reports that the car is doing the same thing. Check engine light briefly illuminates and goes right back off when this occurs. She is able to slip the car into neutral and it seems to correct the malfunction. Unfortunately she has gotten so good at this that she keeps her hand on the gearshift when driving. It seems to happen at various speeds with no warning and no lasting effects.
She came to visit for Christmas and I was able to replicate the problem after about 30 minutes of city driving, but not quick enough to take a picture of the wrench that illuminated briefly. I slowed to the edge of the road, put it in park and turned off the key (engine ran the whole time at idle). Cranked back up and good to go! She had the oil changed about a thousand miles ago, I replaced the air filter last night and she had to return to her house for work in the next couple of days. She said it happened 5 times on the way home last night.
Car has always been serviced regularly and was a certified pre-owned when we bought it in March or so of 2012. I also bought the extended warranty although that may be expired by now.
Her local dealer said they can't fix it if the CEL is not on or the problem is not occurring at the exact time they have it in the shop. Now, I am not sure but was under the impression that the computer would record any codes and store them even if the light went off and the car returned to normal.
Car started to jerk when 30mph and up. I changed the fuel filter and oil. Car was ok for a couple of days, however it started to make lound sounds, needing a muffler. i took it to the shop and it needed a flex pipe. All was well for a day, than the car had trouble staying started. It would drive fine, but when you are stationary at a light or stop sign the car wanted to stop. Took it to the shop and the guy said it need a pvc pipe/hose.
The guy told me that the pipe had rotted and it was at the back end of the engine. Car was good for several days, however it now started back jerking at 30mph and up. It will not do it all the time but sometime. It's like the cruise control is going on off. You can step on the gas, but the car will not go any faster, 'just stay the same speed.' When speed is drop it will be ok, but will jerk for a period of time and then stop.
97 aerostar rear ac stopped working. Blower runs fine. Checked solenoid has power and clicks when plug pulled and refitted.
Liquid line is hot to solenoid and somewhat warm after the solenoid. Return line from evap is at room temp.
Front is 40f at register. Am I looking at bad solenoid or blocked orifice tube. Solenoid is nla. Orifice not so. Still on original evaps comp etc.
I have a 2003 F250 with a 5.4L V8 automatic transmission with 64,000 miles. The truck runs and drives well, but occasionally while driving, it acts like it shifts into a higher gear, slips a bit, then downshifts and runs fine. The duration of this "acting up" is about 1-2sec. It seems to do it when going up a slight grade at cruising speed about 40-50mph. (Not towing when it does it) It doesn't do it all the time. I'm planning to change the filter and fluid but am doubtful that will work. The fluid color is nice bright pink and does not smell unusual.
View 1 RepliesI have a 99 Ford Contour that sporadically refuses to start. The engine will turn over (is that the right term?), but it won't "catch," for lack of a better way to put it. It seems to happen more frequently when the gas gauge is at 1/4 of a tank or below. A dealership told me it was the fuel pump need repair (more than the car is worth), but a second opinion from an independent garage says it might not be the fuel pump.
(Though they don't know what is causing the issue because, of course, it never behaves the same when the mechanic drives it). The second issue, which may or may not be related, is the vibration in the car. It happens only if I turn on the AC or heat. And I do mean shake - it's very noticeable and loud. The motor mount has been checked and that's not the issue.
I just got done with a complete engine rebuild on my 02 1.8t jetta, had everything hooked back up and went to start it for the first time and it wouldn't. I went back looking for loose connections, nothing. Worked and banged my head for a day or two, I had fuel and spark but couldn't get it to fire. Finally I "choked" the intake to see if it was getting too much air and it fired right up. I unplugged my map sensor giggles and it starts up perfectly. I then hooked everything back up and what do you know it starts up and runs fine, but if I plug the sensor back in it kills the motor after about 10 seconds of running and won't start until I unplug the map again.
Car runs and drives but wont boost over wg pressure but that's probably because sensor itself is unplugged. I just wanna know what could cause it besides the sensor itself being bad. I ordered a new one waiting for it to get here (hoping it fixes the problem).. And I'm talking map (manifold absolute pressure) not maf (mass air flow), just in case people are confused.
