Low fuel pressure, maybe..... but, that would cause other issues as well.

 

My mechanic wants to hook it up to the computer and run the codes. I'm not sure this will do much as the CEL is not on.

 

I hate to say it, and the poor sap that buys it will have problems eventually, but have the cat change, it will run great long enough for you to sell it.

 

Well I took off the O2 sensors and wouldn't you know it runs a lot better. Seems we have found the problem. I'll be buying that gasket as soon as I get home. It doesn't idle right without the O2 sensors and it stinks like gas!

 

You are buying what gasket? The lower intake ? If you decide to keep it, replace the plate as well. If just selling it, get shorter bolts for the plate or cut the **** off the end of the OEM bolts, and use a Felpro gasket. This way you are not totally screwing the new owner.

 

Stinks like gas? Does the engine get up to operating temp according to the gauge?

 

Yes it does. I'm buying the Hughes or the EBay gasket kit.

 

I bought one from the guy on EBay, nice clean job on the plate, I would advise to get that, then the felpro gaskets, and manifold bolts from the dealer.

 

I'd gut the cat and sell it as is and cheap if I was selling it anyway.... I mean otherwise your kinda doing the labor for free...for somebody else.

 

Ran the codes and the computer says its a TSB or mass air flow sensor problem. My mechanic is going to get the parts and see of that's the fix.
