the dancing idle is another well covered problem on this site - the simplest culprits could be the throttle position sensor, mass air flow sensor, idle control valve, and fuel pressure regulator - i changed all but the mass air flow sensor and mine has been idling perfect for over a year now - good news is they are super easy and fairly inexpensive to change - might be a good place to start - hope this helpsOriginally Posted by GAMEON
yeah i've replaced the pcv and cleaned the egr. seemed to get worse after doing that though lol. now its been hit or miss. topped it off on saturday and drove all weekend. filled up the fuel tank on tuesday morning and checked the oil... still full. but it did start something new. I was driving maybe 20mph and it started to cough so to speak and then just died. Started right back up though. Did it again about a mile down the road and again this morning on my way to work, but this time i was traveling down a highway off ramp and just died. started right back up though. it was the weirdest thing. the rpms just kinda dropped and bounced back up then... nothing. had to restart it. It was find on lunch though. i've cleaned the throttle body too.
