2000 pontiac sunfire wants to stall out at stop lights or when I am sitting still it is fine on the highway I have changed the fuel filter, the idle control censor the air temp. censor.


if it idles "rough" in conjunction with problem mentioned then try changing electrical components like plugs and wires and could also be partially clogged fuel injector with carbon build-up

When i pull up to a light it idles rough and will stall. it does start right up i replaced the ivac motor still idles rough when i slow down to stop and start


It could be a sticking torque converter lock up solenoid (TCC solenoid). Try unplugging the green wire connector on the trans to disengage the solenoid and see if it still stalls. Sometimes flushing the trans fluid helps, but other you need to replace the the TCC solenoid. You can do it yourself without removing the transaxle (you just need a repair manual and socket driver set that includes torx and hex or allen head bits).

Engine sputters like it has bad gas


Firstly check for any air leaks or split pipes under the hood you can normaly hear them sucking. Air leaks can make the car run lean but usually will also make the car run rough or nealy stall when going from cruise to idle.
Sounds like it might be bad oxygen sensor(s) they are used to sense the fuel mixture if they go bad the car can run lean or ritch. This can be confirmed by taking it to a mechanic and reading off the ecu codes (or you could invest in a device for doing this). That will confirm before investing in new sensors.
Hope this helps
