    Anytime my car is at its peak temperature, if i floor the peddle the engine starts spuddering, that SES light flashes, and i can smell unburned fuel comming from the exhaust. Obviously theres sum missfiring goin on but why when the engine is hot? What could it be?

    You need to see what codes you have stored. Could be a bad MAF sensor. Could be a lot of things. Go to auto zone and have it done for free.

    I know for sure i have an 0440 code being thrown right now. Guess it has to do with the evap system.I have checked all over for leaks and replaced rotted rubber hoses and such. Could this code have sumthing to do with the engine spuddering. When i went to autozone they checked the SES and told me i just needed a new gas cap which was bull****. I already replaced it before i took it to them to scan the SES

    had car scanned an the codes were 1133, 300, and 440. 300 is multiple missfire. 1133 is second bank 02 sensor, and 440 is evap. Any ideas anyone?
