Torquer V.2 idle without tune? 2004 GTO m6. Installed cam and 243 heads. Started the car on manifolds only and idled great with no check engine light. Put the rest of the exhaust on, installed and connected from o2's and the backs are plugged off. Now the car is hard to start, will not idle but runs fine going down the road. Have to keep on the gas at idle to keep it running. Normal? Why would it idle on just manifolds? Just wondering, car is getting tuned this coming Monday.

Back pressure has nothing to do with anything.. the scavenging is what your trying to get at.. IMO you changed **** around with out changing the tune.. on the newer cars they have electronic throttle bodies and such, the idle probably needs to be relearned.. and as with any serious mod i.e. cam i would get it tuned asap, you dont want to ruin anything by running it with the air fuel ratio off. Its probably nothing more than a tune issue. If there is a gm dealer in the area you could bring the car there, and try to have them relearn the idle for you.. that might at least get it to idle.
