Ok, ive exhausted all my mechanical experience (6 years as a mechanic by trade) And this car is driving me up the wall, I cant find any information on the 2008 and its getting ridiculous, From what Ive read I have a IACV that needs to be either cleaned or replaced, problem is I cant find it and I cant find out if I even have one on this year of the Scooby. The car is pretty tuned up. Basically what happens is when I start it up cold it idles at 1500rpm, and when it gets warm it hovers from 700rpm to 0rpm almost stalling, and I got no codes coming up. goin from 1-2 gear I get full range no issues hit 3rd gear I get some hesitation (very noticeable) at around 3000rpm and it does the same all the way through the gears from there on out. Also if I really romp on it I get no hesitation. full power. Anyways as ive said before it seems I have a IACV problem. I also should mention that ive cleaned my air filter and my MAF sensor.
