i did a lil research while i was at work last night and some people have had pretty much the same problems... They all kept saying that when they went to brake, let the foot off the gas (like @ 15 mph on mine), ac kicks on, turning at slow speeds ( in a parking lot), that their rmps and voltage drops and on occasion the vehicle will die... Some mechanic had stated that the idle speed is all based off the computer. So only upping the idle will or can cause other problems down the road.. Said the best thing for us to do is get ahold of some deep creep and clean out the throttle body and get rid of the deposits that the computer cannot account for and also get some mass air flow sensor cleaner and clean that as well.... im gonna go this route but im gonna leave the maf alone and tack on the big 3....
