the other day i started my 00 gt and it was acting funny, it would act like it was going to die then it would jump back up to idle. after a while of driving the cel came on, so i took it to the dealer and they said i needed to change my spark plugs. i changed them and it started running normal again but a couple days later it came on and started running weird again. it will come on after a couple days of driving and im lost. can anyone give me an idea of whats going on?
You need to find someone good with a scope. It could be a number of things...from the crank shaft sensor to the ecu. It may cost you money. Lots of it. But if its under warrenty make the dealership fix it as long as you only pay for thedeductable once. Also what was the code? email me at redbullktm1212@aol.com and let me know what the cel code was. I'll help ya out.
