NEW ISSUES, JUST IN TIME FOR WINTER! WOOHOO! I got my car tuned last weekend (On that note- +35hp and 16tq on E85. woo!). After taking it for a decent amount of miles (about 75), it started to stall whenever I come to a stop with it in gear. It seems to cruise allright, and the idle is smooth. Heres what I have done so far: -new motorcraft O2 sensors -checked for any vacuum leaks -replaced the MAF -cleaned/tested IAC (died as soon as it was unplugged). However, it doesnt idle where I set it to in the tune(IE, 900 is 700ish and 1000 is more like 800 or 900) -In the process of a hard ECU reset, with a fresh tune file (same one, new file) Im at a loss on this one. Asking friends, Ive been told a few possibilities- corrupted tune file (hence the reset and new file), clogged fuel filter (had to drain tank to go E85), bad TCC Solenoid/locked(or bad) converter. Help? anyone? Oh yeah, specs- its a '02 3.8 with a 4R70W.
