Welcome Visitor! Please take a few seconds and 
So I've completed my 2.3t swap from an '88 T-bird. The problem is the idle when the IAC is plugged in is 2000rpm. I found that the TPS was at fault and adjusted the idle without the IAC plugged in and got a new TPS and got it idling at 800 (without the IAC plugged in). Once I plug the IAC in it jumps up to 2000rpm.
I've pulled codes and got:
12-Idle Speed Control motor or Air Bypass not controlling idle properly (generally idle too low) - ISC (I left it disconneted during the test so the engine wouldn't be screaming in my ears while I was doing the test)
26 - Vane Air Flow (VAF) out of range - VAF (I accidentally left this unhooked last time I ran it last night so I'm wondering if this is why the code showed up?)
34-EVP - (R) EGR did not respond properly during test - EVP (its not hooked up)
41-(R) System lean - Fuel control (could be because I left the VAM and IAC unhooked during the test?)
Anyone have any ideas?
