First post but nowhere near new. I've been lurking for quite sometime. Im in a bad spot guys and I need your help!! Here's the deal....
I've had a surging idle and gurgling sound coming fr my intake. My knowledge tells me IAC (you can pinch off vaccum and it stops gurgling). I replaced this thing with 3 different IAC with terrible side effects. They are as follows.
High idle followed by engine stall/die.
Horrible horn sound.
I looked intO the intake port of the IAC and all the new valves have a spring loaded plunger type thing, my old one does not. I also noticed Ford lists two iac for my car...are they different???
I really need to get this thing going as its my daily driver. I have re-installed my old valve and it just has a slight gurgle and fluctuating idle (200-400 rpm fluctuations).
The gurgle started intermittently and is now consistent. Car is stock except for 150 wet shot and programmer. I have returned the tune to stock for now. I've cleaned the IaC with the same results.
My computer reads nearly stoich with old IAC and with new IAC it reads +32 ST FTRM (both banks).
Help!!!!!!
