When I start my engine (355 TPI) it sometimes stalls right away, if it doesn't stall it stumbles for a second then idles pretty good. The only time I notice a problem while driving is near WOT from 1st to 2nd shift (700R4). Any ideas as to what is going on? I ruled out the MAF b/c I had another one to test with and they are both operating fine. Does this sound like a timing problem? That's the next thing I'll try. If that doesn't solve it, where should I go next? I'm getting no trouble codes.

 

Oh yeah, about that WOT problem...the engine just hesitates. Unless it's a tranny problem, but I don't think it is.
