I have a 2000 V6 automatic and every once in a while when i stop at a light or put it in park the idle will be fine for a few seconds then it will drop and the engine vibrates when it gets real low then the idle goes back up. sometimes it will do it over and over again. it never dies. i checked the iac and cleaned it yesterday but this morning the idle droped and went back up...just like always. could it have to do with the air intake?......[>:]

 

Chack all the hoses for vacuum lraks

well....i think it was just the iac because it hasnt done it since the other morning as stated before. i checked everything and it was all fine so i think the iac had just a little more gunk in it that needed cleaned out....thanks for the help though.

 

hi again. i am still having the same problem. so far i have checked for vacuum leaks, i have cleaned the iac, cleaned the throttle body, and cleaned the maf wire. i wont know for sure for a while but it seems to do it more when its cold out. any ideas?
