The power loss and fuel usage is getting worse. The convertor is ok, and I have the new Mitchell on demand car repair cd's and have done the re-routing for the plug wires for the spark knock on accelerating. ( Still has spark knock) I have also checked for vaccum from the pcv valve just in case the plentum gasket was going bad but that checks out ok as well. No check engine lights at all, no codes either. And to answer there is no fuel coming from the tail pipe either, no oil loss,
Just trying to see if this is a simple hard to find repair or should I pay big money for a dealer with the right computer to check it out for me. Seems I have done every thing I can my self so far, But this truck takes off like a 4 cylinder and uses gas like a fleet of cars.
Any other help would be great
