Performance Issues
Ok, guys I've searched and searched and don't know what else to do. My car is jumping. Yea, I said jumping. When the car is in drive and my foot is on the brake or the emergency brake is on. You can feel the car jumping and the RPM's keep falling (only slightly). And today when I was driving and having a real bad case. I speed up to about 65 and the car just shut off in the middle of the road. I pulled over and cranked it and it started right up with out hesitation. What's going on. I've seen others that say the replace thier ignition coils and sometimes this fixed their hesitation. Does this sound like ingnition coils? What do they actually do? I never have a problem starting the car or any thing else. But it just hesitates and jumps(sometimes). Also when driving sometimes the car is fine, but I will just be driving along and the RPM's will rev up like I'm stomping on the gas. So then the car will try to down shift. Man I need help. Any suggestions will help.

Ummm...., what are the odds your cruise control button is set to 'on'?
If your cruise is 'on' and is malfunctioning, then that could cause this.
Otherwise, I'd be thinking bad sensors, or dirty connections to those sensors.
Sorry I couldn't be more helpful tho.
