hey guys, same problem here (I FEEL YOUR PAIN!!! IT SUCKS!!). engine boggs is sluggish and unresponsive when outside temp is 60F or below and until the temp needle is out of the blue, although it idles on it's own alright unless its in the 40s outside, but even then it holds it's own. all my resources (mostly you guys) have led us to believe its the AFM, however the O2 sensor and coilpacks seem like a high possibility. We've gone through the same motions as well, replaced all the coolant hoses, coolant temp sensors, camshaft pos sensor, intake bellows. TPS seems to be working as per multimeter specs, and ICV killed engine when we unplugged it (although no audible 'buzzing'), so it's assumed that it's working as well. Haven't tried testing the AFM (trying to find one that won't break the bank) or seeing if the O2 sensor is too bad to work. Have you tried those fifty?
