Title: What Could Be These Symptoms?
Post by: egspot on October 07, 2006, 04:32:14 PM

OK so the engine starts and while there is another motor on the works, I want to find a way with the current engine. The engine starts and idles fine. There is good strong presure comming out of the tail pipe until I rev it. I do not know why the forced hot air drops substantially.

Any ideas?

Not DVKK but....

Does it have a DVDA distributor? That'll make for strong exhaust pressure at idle and much less when you open the throttle. Don't worry about it.

diffuser valve wtf are you on? its got to be the inflection controller, and the only way to fix that is to rewire the distributor

My DC had the same issue. After hours of diagnostic tests I found it to be a faulty rectal diverter valve.

never even thought about that, an easy fix for that is rear end lube job.
