Hmm exhaust problem now?

[warrioralumni08]

Well, my exhaust is fabbed up. With open manifolds, it would start right up and run. With the new exhaust, it took a couple times to start up, and had to give it gas to let it get idle. Stock manifolds, no cats, removed third muffler and cat, has a long Y going into the single stock pipe, exiting into duals. Maybe not enough back pressure? Or probably my idle air messing up? I would rev it up and it would die down quick and stall. Any help is appreciated.

The exhaust isn't your problem.

Sounds like a vacuum leak.

Ill check it out and see then, maybe a vacuum line is no good since they have been sitting for a bit. Maybe I broke one, who knows. I want to lean towards the iac, but don't want to spend anymore money.

Easy way to check for vacuum leaks: with the car idling, use a propane torch (not lit, of course) and spray propane around the top of the engine. If the engine races up, you've found your vacuum leak.

are your o2 sensors in and working?

Ah, very good idea! =] Thanks alot!

Yes, they are in, I will have to check if they aren't working. Should be fine though.

Also, I drove her around for the first time today, runs nice and smooth, but it takes a couple seconds for the rpm to drop down when you let off the gas, like it's sticking. Bad tps maybe?
