I recently bought a 94 mustang convertible with a 3.8 v6 and an automatic tranny. I got the car cheap because the head gasket was blown. I got it to the house and removed the heads. when i removed the exhaust manifolds the pupes were left open, and when the head was removed some antifreeze got into the pipes. anywho, i got the heads re-done and got the new gasket set and so on. i get everything put back together and i start it up and it runs really bad. it wont idle worth a crap and it smokes really badly. the smoke is white so im guessing its the antifreeze that was left in the pipes burning off the cat. sntifreeze also drippes out the tail pipe. anyways, when its running, i hit the accelerator and the rpm doesnt increase untill i let off the throttle. its like the rpm's increase only after the throttle blade closes. i am running the motorcraft plugs and motorcraft wires. I am at a loss here and i need some help. while i had the upper plenum off i removed the throttle body, IAC and EGR and cleaned them throughly and sealed them up with new gaskets. if there are any test i can run or any suggestions at all please let me know.

thanks
