My '02 Z with 112k miles on her runs very well, but when the car gets warmed up in vibrates a little bit a stop lights and at idle. I had new plugs and wired put in last week, but it did not fix the problem.
Any suggestions on what the problem could be? Anyone else had this issue?
I just got the car and don't really know the history on it... It was maintained well and adult driven, but that is all I know.
For stock the cam is reasonably aggressive and will shake some. Gets more noticable with the A/C off. It seems to be smooth with a touch of shake and then every so often almost shudder. Mine has been that way since the day I bought her new.
Hopefully that's it, for the most part things are pretty solid, (except the valve springs, change your clutch fluid a lot, and watch out for deep puddles)
You should check your fuel injector wiring harness on the driver's side of the car. It can rub through at the back of the cylinder head and short one or two injectors to ground and cause a miss and vibration. Happened to my car at 40,000 miles, found it and now runs perfect.

My 2003 does the same. Most noticeable when warmed up and A/C is off.
