2000 pontiac sunfire and it hesitates and stalls if I'm not moving. ?

Question

I have a 2000 Pontiac Sunfire. Lately it has been hesitating and stalling if I'm stopped. This has been going on for a month or two. We had it looked at but the 3 things they said it could be we had fixed. and we changed out the spark plugs/cords. then just the other day my check engine light came on. Any ideas? My RPM's aren't at zero when Im stopped either. Do you think it could be the idol is off?

Answer 1

Bad piston slappings. Try adjusting your Piston Slaptron Sensor.  

Answer 2

not sure.....could be a clogged fuel filter....pressing the gas forces it through more than when it is idling...good luck.

Answer 3

My boyfriend who is one month away from completing college for his ATA (Automotive technology) degree said mass air flow sensor.

Answer 4

fuel filter and fuel treatment alway something people forget to do  fuel filter once a year fuel treatment every other month

Answer 5

An earlier joke answer could just have easily said muffler bearings or add a can or horsepower.

Now that you have a code, get it read and determine the cause.

It is a misfire, but why?  Often the 02 sensors are faulty, and catalytic converter clogged.  It gets worse in the heat.

Also, a nice new Aero exhaust, world's highest Tech based on jet motors would be a great idea.
