2002 Buick Rendezvous CXL will idle very high & idle too low & stall when going slow or stopping.Replaced IAC valve. Service engine soon light not on, but service vehicle soon light always comes on.


Check for applicable trouble codes. Some of the national brand auto stores will check codes for free.

You may need to clean the throttle body and clean those small passages. With a high idle block off mouth of throttle body, should have a big effect on the idle? There are several issues that could cause idle to act up. Vacuum leak--maf and or map sensor. Don't replace anything unless testing points you in that direction.

I meant how do you replace an egr sensor in a 2005 rendezvous?


A faulty egr would not create a high idle issue. if an egr valve were to open while idling then it would create a heavy stumbling engine or it would die right out. if there is a check engine light on (or service engine soon light) have the codes pulled. Failing that then I suggest taking it to a reputable shop

Have to mash gas pedal on 2007 buick rendezvous to crank, after starting it will idle fine but sometimes die for no apparent reason, what would cause this?


Test your fuel pressure for leak down while sitting.. It should hold 52-59 psi... If not it could be a weak fuel pump..Also test the fuel pressure regulator to see if its leaking gas into the vacuum lines.. Alot of times you can do this by running the vehicle then leaving it set for 45 min and then removing the vacuum line at the fuel regulator and checking for wetness... If its wet with fuel its leaking and needs replaced..

REPLACED STARTER AND BATTERY,BUT ENGINE WONT STAY RUNNING WITH OUT FOOT ON GAS?


you may need to clean the throltte body, and then start the engine and hold the rpms high for a minute, then slowly reduce the gas pedal to idle, you blanked out the memory, now it needs to learn the idle speed again.
