Did you have the computer checked on this motor?
Any fault codes/reports?

We have quite a few of these motors running, but have not run into a problem like this (yet?).
Just a shot in the dark, but is the iac valve working right?

Greeitngs,
Gerben

gerben, have been thru computer from one side to another, the only thing i have not tried is replacing comp. we have had 0 troubles with them until this one. motor did have an iac valve problem but that only fixed the idle. i have currently been whooped by this one but am willing to try anything at this point, would try another computer but can't get any customers to let us try theirs i guess they are afraid it may zap theirs and i guess i can't blame them. the worst problem is that it is not at any specific rpm or condition and it may stop tomorrow for a month and them come back again.
