Thanks. I'm still chasing the misfire problem.....I'm looking at the coil packs next. Still need to clean up the connections to see if that helps.

I wonder why it only misfires when it's idling?
Can vacuum leaks cause misfire?
Vacuum leaks cause most misfires!
When you give it throttle, you have less vacuum which is less leak.
Well how in the heck do I check for vacuum leaks?
let it idle, spray carb cleaner at all the vac lines and sensors, if the idle jumps up, you found a leak area.
Ok. Thanks. I'll try that. The car runs perfectly with no misses until it warms up, so, maybe a vac leak is the problem.
spray the injectors too, the TB as well, around its gasket area and vac lines.
may want to pick up a used icm, never know, they do go bad.
what's the silver thing in the picture? It made a air leak sound when I moved it with the car shut off.

Fuel Line connection.
You have a boost gauge that shows vac on the car don't you?
If so whats the vac reading at idle?
Just warmed it up and checked. Between 19-20. What should it be?Quote:

vacuum seems very steady.Quote:

It couldn't have been running to well though, right?Quote:
