94 LT1 Rough idle
Hello all,
I just put new plugs in, the car was idling really rough, and on the first crank up after putting the new plugs in the car ran perfect for about 5 minutes until it came up to normal temperature. After warming up it started running just as badly as it had before I put in the new plugs.
Before I put the new plugs in the misfiring was there all the time. There are no trouble codes. What would y'all suspect? I haven't changed the plug wires yet, and the Opti has about 38K miles on it.

Yes I did, and since my last post I've narrowed down the rough idle to the passenger's side. I've got new plugs in there but the wires have about 40K miles on them so I'll change them out next. Looks easy to do on that side.
Would a bad Opti cap cause a miss that rough on just one cylinder?
