Well I took my itb's off and now the car seems to back fire a little at idle, there are small some puffs from the tail pipe ( back firing ) and when you stomp on the gas it back fires a lot more. When I was checking for fuel leaks I left the tps on accident, well I actually tried cranking the car twice with the tps off, so could the back fire be the excessive fuel just burning off ? Also if it makes a difference, I have no pcv at the moment. I have the manifold line blocked off and the other line just hanging. I don't think this would cause it but I want to hear what others think.
I have a fuel psi gauge and the fuel pressure seems fine. Its around 35 at idle.

Maybe your running to lean?

 

Well I changed the plugs, it seemed to fix the problem. I have not really got to test the car out so I'll see what happens.

 

ahh.. mine are gapped at .042 and it runs fine

Yeah same here, well .042 to .044 , hard to get exact with the gapper.
