you might want to check your egr valve. if it's stuck open and leaky just a little bit it will almost kill the engine. it's easy to check if you have a vacuum pump. they are cheap and available at any auto parts store. the procedure is in the chiltons manual. if you need more detail just yell. I'm having a similar problem. my idle is going up and down randomly. i'v checked every sensor that i can and everything checks out good. while testing the idle air control valve i found it was making the idle change but it was because its signal voltage was changing. the only thing i haven't changed is the pcm. any ideas?
Reset error codes, Oxygen sensor is ignored if old errors are not cleared.
The idle going up and down, depending upon how erratic, may be normal behavior during the warm-up process. Check the timing belt and make sure that the timing marks are still in alignment. Unfortunately checking the timing mark on the crankshaft requires removing the damper. Otherwise it'd be cake.
Could be MAF (Mass Air Flow) sensor. Located between air cleaner box and throttle body. I was having the same problem I unplugged the MAF sensor and it ran better. So, I replaced it and it ran even better yet. I replaced the fuel pump and fuel filter before that. But, it still ran rough. I tested fuel pressure and it was fine.
i changed plugs wires throttle p sensor an checked fuel
If it hasn't been changed, it has Throttle Body Injection (TBI). It looks similar to a carb but it will have wires running to it.
Probably have a misfire or lean fuel mix NELSON
Throttle position sensor is located on the side of the throttle body-in line with the throttle shaft. To locate the throttle body, you can have someone repeatedly push the accellerator pedal (with the engine not running) while you look for the moving throttle shaft. Drew
change the thorttle responce
Any bad component can stop a car from running. Throttle body? probably not.
The throttle position sensor determines the amount of throttle used when the engine is running at various speeds. If the sensor is faulty, it can be replaced by ordering a new part.
Only one forward pass is allowed per play where there is no limit to the number of lateral passes per play (a lateral pass being one that travels parallel or backwards to the line of scrimmage). If the pass to the running back is a lateral pass, the running back is allowed to throw a forward pass to the receiver. If the pass to the running back is a forward pass, the running back is not allowed to throw a forward pass to the receiver.
Put a used one on from a running one
probably failed throttle bypass solenoid or possibly throttle position sensor
Passenger side of engine next to throttle body. It is the senor with the vacuum line running to it.
if the car is running rough whilst idleing or running, simply unplg the airflow meter and test drive the car. if the airflow meter is buggered- whilst it is unplugged it should run fine
Could just be throttle plate sticking--without engine running try to free with a screwdriver Could just be throttle plate sticking--without engine running try to free with a screwdriver
I changed the EGR valve, PVC valve, now it has gotten worse. I also cleaned the throttle body.
It would depend on what the problem is. All throttle problems can lead to a non running engine.
A bad throttle sensor can cause engine jerking and rough running. A test of the computer codes should show if there seems to be a problem with the sensor.
throttle body sensor is a sensor that regulates gas flow. if your car is running sluggish sometimes this can confused with transmission problems when in all actuality its the sensor
A balance disorder.
If it is stalling when putting it into gear but not while idleing I would check your mass air flow sensor. It may need to be cleaned or replaced. If it is stalling when putting it into gear but not while idleing I would check your mass air flow sensor. It may need to be cleaned or replaced.
you could have a bad fuel injector if dirt gets into the injector it will stay open
People running should be drawn with their legs spread far apart, and looking forward.
Daphne was running from Apollo, and she was running out of breath. She prayed to her father and he changed her into a laurel tree. Thus, why we see Apollo with a laurel crown.
