3 months after ZE swap i get my probs, need a suggestion

[thebox]

So my ZE was running fine since the swap until like 2 days ago. Suddenly my car starts misfiring pretty bad, and the idle is terrible. Not only is the idle rough as hell from the misfire, but it jumps back and forth from 500-1500. The idle doesn't jump around a lot, only every now and then (like on a 20 min drive, if i stop at 3 or 4 lights, it will do it on 1 or 2 lights). If any of you have tried the "coolant bypass" thing where you take coolant lines away from TB, it gives you this same type of problem but only in cold weather. I know this from experience. I do not have my coolant disconnected from the TB after dealing with that. Now it seems to be doing almost the same thing but not as bad, plus there is a big misfire problem too. What do you think would be causing this? Plugs and wires are new from when I did the swap. Would disty be problem? It just doesn't seem to me like the disty would be causing this type of problem. My car doesn't smoke at all... as far as I can tell there are no vac leaks. What the hell is going on?

It may be your VAF. Try to find a PGT VAF and see if that corrects the problem.

Other than that, I see you have the ZE ecu and MS8 IM so it should all work in sync.

Also, try disconecting your battery for about 10 minutes, reconnect and start'er up and let idle for a few. drive gently and see if that helps.

Thats all i can think of.
