windy Posted June 17, 2010 Share Posted June 17, 2010 I posted a problem earlier today. However, one other problem is that when it does not crank properly, it idles rough, especially if the air conditioner is running. Also, if I'm accelerating down the road, say around 50mph,the motor will hesitate and the rpms will drop. When I accelerate just a little, it will come back to normal. I have already put a throttle position control, new spark plubs, air idle control and had my muffler replaced. No codes show up when the motor has been checked. Also, my check engine light has never come on. Still needing help. Quote Link to comment Share on other sites More sharing options...
