Could this be it......
I have been suffering from misfiring for the past couple months and still cant figure this out...It only misfires for about 10sec when driving after the car has been turned off for an hour or so...This misfire usually happens within the first mile of driving then it misfires and the car is perfect till the next time it gets shut off and sits...I have checked plug wires and car has bran new plugs from when nitrous was going to go into the car...What do you guys think could be it...I have came to a few conclusions...
1)The tr6 plugs with the small gap for nitrous
2)O2 sensors took a crap on me
3)Maf took a crap on me
Let me know your ideas....
Thanks,
Kyle
