cel random misfire
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?
