Idling rough and hesitating when accelerating


This sounds like the mass airflow sensor.

Trac Off light and Cooling Fan running on my 2001 Chevy Cavalier


I had the same problem on my 2001 Sunfire (same car as the Cavalier-different branding) which I was able to fix successfully.

My symptoms were:
-Traction Control OFF light illuminated
-Cooling fan running even if engine cold and it was freezing outside (I also noticed that when the Traction light illuminated, the fan would then begin)
-Rough idle with black smoke when cold
-Poor fuel economy


I have a code reader which produced codes P0130 and P0171. These are error codes for the upstream oxygen sensor (the one under the hood).

I simply replaced the O2 sensor (it took me 10 minutes). I did not reset the check engine light after the repair as I wanted to see what the car would do on its own. The idle was much smoother with no smoke and the cooling fan stopped running unnecessarily. After 1/2 mile down the road, the Trac light went away and the system functioned normally. I tested this by trying to accelerate quickly up a snowy driveway. I also noticed that the acceleration and shifting (auto tranny) were smoother. I reset the check engine light. All is satisfactory.


What was happening to the car before the repair:

P0130 is usually for a bad O2 sensor and P0171 is the sensor detected that the motor was running too lean (but it actually wasn't-the sensor was essentially giving a false lean signal).
The rough idle, black smoke, and poor economy are due to running too rich. In my case, the sensor told the PCM (the car's computer) that the air/fuel mixture was too lean. In response, the computer said "OK, more gas!" That's why it ran rich. This was evidenced on the old O2 sensor as well...it was completely caked with carbon from an excessively rich mixture. This further destroyed the performance of the O2 sensor.

I have a 2005 Cavalier that after I drive it a while it starts jerking when I accelerate. If I am idling and rev up the motor it starts racing up and down. The code it s throwing says it's the o2


Its possible to have a faulty O2 sensor, but the sensor could also be telling the truth - that the fuel mixture is off.
Usually the O2 sensor codes mean the data the sensor is providing to the computer is out of range, but the exhaust really could be very rich or very lean.
A mechanic would use a scanner to "read" the sensor and he would also check the fuel pressure among other things.

My 93 ford taurus gl 3.8 liter v6 rotates but will not start after it rains or is overly humid outside. then if it does start it idles rough and lacks power. ive replaced the distribitor cap, motor bug, O2...


Brian, I would take a spray bottle filled with water and start car. With the motor running spray all the plug wires and coil wire. if it starts to miss or run rough replace your plug wires they are bad. If it runs the same after spraying the plug wires try spraying all electrical connections til it starts to act up.
Hope this helps Thanks for using FixYa.com

it sounds to me that the sensor your talking about is the camshaft positioning sensor. It regulates how much fuel you get to your engine, so that is also why you have the fuel smell as well.

Engine runs rough after about ten minutes /idles really low


Just trowing some suggestions out there, but, I would check the idle air control valve (solenoid) or the throttle position sensor. If they check out then my last guess would be the map sensor or the vaccuum to the map sensor. Hope I was able to help. Best wishes.

sounds like you left something out. check to see if you plugged in all the sensors and plugs, then check for any vacuum lines that were not replaced or may have been broken

1989 Cavalier Z24 3.1 rough idle and hesitation


It sounds like you may have a broken exhaust valve spring, although, like you have found out problems like this can be very hard to diagnose, but anyone with a compression tester and couple other tools could find out if this is the case. Hope this gives you another idea where to look.
