Hello Commodore Knowledge.
I am fitting an intercooler to my V6 and am having problems with reverse plenum It is a VR v6 with a side mount powerdyne CAPA kit, with a custom made inlet manifold to reverse intake. The manifold is just a standard vr with the top chopped off and a ecotec top welded to it. It runs the ecotec T/B which i have extened both sensor plugs for the throttle body.
At the moment it is running N/A so i can fan out the bugs.
So my problem is that the car will drive fine under acceleration but if you try to maintain a constant speed, the engine revs die and only come back on once more throttle is applied.
I have checked all wiring, replace TPS and idle step motor and many other things . The only thing that i can think of is the ecotec throttle body is causeing the drama.
Any suggestions welcome cause i am out of ideas
have you checked for any vacuum leaks?
Yes all lines checked with vacum guage, and some replaced gonig 4 another test drive now.
the best thing would be to hook up a laptop and datalog with software like EFIlive. software is free for trial purposes and a ALDL cable is fairly easy to make or you could possibly buy one from someone on the forum
