hey guys thanks for the input, havent had much time to take a look at things myselft but luckily I was able to get it to a dealer and have it checked for free. Here'* what they found: Misfires on cylinders 3 and 6 - no spark on those. Ignition control module is apparently causing the misfires. How much would one of these run or does anyone happen to have an extra one?

Finally got the new ICM and installed it yesterday. Car runs much better but there is still a ticking sound. I believe I have a bent pushrod according to the dealers diagnosis. How difficult is it to change out a pushrod? I opended up the valve cover yesterday to take a look and I think I will attempt this once I can order a new push rod.

I have a few used sets of pushrods laying around if you are looking for a low cost set.
Pushrods are relatively easy. Pull the valve covers, remove the rockers, then the pushrods can be removed and replaced. Using reusable rocker bolts, reassemble.
Oh..BTW, I have those too. Your stock bolts are torque to yield and are not reusable.

Bill make sure your "spare" parts are not what he needs. Did we notice what kind of engine he has. Or does this not make a difference what he has referencing the pushrods?
