Does any one know how to fix the low rpm stumble? It only does it when the temp gets hot(usualy above 190).Once it gets to about 2k rpms, it runs great. I've changed the plugs,wires,coil,coil module,opti,fuel filter and pcv. Any ideas? I'm tired of throwing $ at it, and getting no where.

far as i can tell you have done the what you can do, i would try and find someone who has a tech3 scanner and check out the car completely this may help you out, does the car run normal at idle?? have you checked your egr system lately? i had a stumble once at really low rpms and went through alll the changes and after i checked the egr system and all was fine hope this helps.

Check all the wireing going to the manifold air pressure sensor(mines on top of the intake).My02

did you figure this out? Mine is doing the same thing, except getting a little worse. Today it stumbled at about 2500rpm. So I have to find a solution before it gets worse. Otherwise what's the point of having a v8 if it won't accelerate fast?

It's probably not a part going bad... you need to check wiring and make sure all sensors/connectors are situated right. I'm sure it's something simple like that. I have a low rpm bucking but that's a result of my exhaust leak. If you have one it might be causing it. Good luck.
