Recently, I've noticed a rough idle at stops and I only have about 20K on my 2k max. I was wondering if the platnium tipped plugs are going bad or something? Could also be a number of different reasons for this, but that is my first check point. Has anyone swapped out their ignition system for a aftermaket one? Like the MSD or Jacobs? Plus I thought these platnium tipped plugs were supposed to last us 100K! I guess they didn't factor in driving the car hard everyday huh?

 

bump:

What does anyone know anything?

 

Could be a lot of things...

Bad or fouled spark plugs, dirty air filter, leaking vacume line, bad ecu, clogged fuel injector....

I have a slight vibration felt in the steering wheel, don't know what it is.

If you want to get rid of it first check the basics as noted above.
