[QUOTE="Ted B, post: 16092459, member: 193850"] ok well the hesitation turns out to be a mix of the AIC not being able to seat inside (it ohmed out ok 9ish, vs 10.0 on the new one), and well just shitty spark plugs. so on the up and up she purrrrrs like a kitten but still stalls out sometime for what seems to be load on the engine. Now this could be caused by many a thing...the AC, the fans turning on however now the New IAC seems to pick up the slack and regulate idle rpms like a champ. I mean night and day rev feel its like having the engine balanced. So onto the down and out...the car now falls on its face and the AIC can't seem to keep her running when to much of a load is put on the engine at idle. However the worst part is now the car feels like a stock mach 1, like i just lost 150 bald wheel eagles on the road somewhere. Car revs out just fine has what feels like stock top end power...feels good down low due to 4.10s, but yeah it's like the blower isn't even on there. I know its there i hear it building boost, and purging like it should, but if the rumors are true and my car has lost its tune WTF over. Now the big question is, can I somehow check to see if the ECU has the factory ford tune, or an aftermarket tune? My secondary question would be how bad could casual driving short distances be with the car everyday...i commute with it like 3 miles. [/QUOTE]
