#1 of 3 Help Please : High Idle Problems w/ 00 Chevy Venture by melissa18 May 17, 2009 (5:43 pm)
I am hoping someone can help me. For some time my 2000 chevy venture was leaking water and oil and at an idle the vehicle would run extremely hot. About a month ago I brough it in and per the invoice the below was replaced :   Intake Gasket Set Valve Cover Gasket Set Thermostat and Gasket Oil Filter w/ 4.5 qts oil Oil pump shaft o rings oil ring for heater hose   Below the invoice it also states : Radiator needs to be flushed ( why the mechanic didn't do this not sure ).   A couple weeks after getting it back the idle starting running really high ( sounded like the engine would come out from under the hood ). The service engine soon light also came on and lasted a couple of days. We were going to bring it to autozone for the code but then the light went off and has not come on since about 3 weeks now. Every once in a while I will begin to idle extremely high again. Problem is I will never know when it will do this and even while it does it the service engine light has not come back on. I just paid $700 for all the above. Does anyone have any idea why it would be doing this and what I can do to fix a problem that now seems to come and go ?   Thanks so much !

I had the same problem. It's probably a vacumm leak. By process of elminiation, I started replacing the vacumm lines. In the end, the hard line from the intake boot that runs to the rear intake valve cover was the problem. It was actually loose, but I couldn't tell until I rotated the motor.   Car's been fine ever since.
