I never really heard much about it...Until i had to reserching my stalling problem.I read you should adjust this if your car is running poorly(hard starts,poor acceleration & milage ,ect)Well,I have to tell you guys that after turning it a little more than a quarter.The car accleration is way better.I no longer have to press the gas to start.And it hasnt given me any heat issue stalls.I'm not siked yet though. everytime I think the cars good, something alse pops up.
