[QUOTE="DSG2003Mach1, post: 16376110, member: 16477"] Since you've made this thread just keep it all in here, don't bounce back and forth between this one and the one mods split out for you. you need to use MAF specific cleaner - other electronics cleaners tend to leave a protective film, this will cause problems. With the car not running for so long I'd try to just let it idle for at least 10 minutes with the AC off and dont touch anything, give it a chance to re-learn. If the idle does settle down turn the AC on max and let it idle a while longer (keep an eye on the fan/temps in case its not kicking up to high speed or something). If that doesnt fix it check the K&N tube from the back of the maf to the TB for any possible leaks. The Idle Air Control Valve has one connector and 2 small bolts holding it on, can try cleaning the hell out of it with carb/TB cleaner and let it dry then put it back. If idle improves just note you'll likely have to replace it soon. Short of their being an actual chip in the PCM (not likely) theres no real way to verify the tune. You could always buy a handheld with a tune and it will load just fine. Then at least you know what you have. [/QUOTE]
