car wont idle

[JAESPEED]

I just had my intake manifold ported and doid my intake.the car starts and runs , but wont idle.I think its the maf sensor because if i unplug it the car stays on at a pretty hi idle.once i plug it back in it shuts down.am i right or could it be something else.oh, i also installed headers and didnt hook the EGR back up,could that be it?

Dude, sounds to me like you have a massive vacuum leak. Take some ether (starting fluid) and spray arond the gaskets for the intake and all other connections for the intake. If, while a lower but constant rpm, the rpms rise, this shows a lean condition which would be your vacuum leak. Move the spray around the area when the rpms rise and issolate where the gasket/connection leak is.

I agree. Check your vacuum hoses also.

Sounds as though your MAF could have had it. Check everything out as mentioned above as well.
