Question about 2002 Buick Rendezvous

1 Answer

I have a question wrapped in a concern regarding my Buick Rendezvous. Just within the last couple of days, I have noticed that when I am in park and while stopped...let's say in an intersection, the idle ramps up to an unprecedented 3000rpm. I know this is not normal. My question to you: what is causing this and what can be done about it. If it is something serious, how soon should I have someone look at it and how much do you think the repair cost might be? Thank you for your time.

Good Evening, from the sounds of it you might have a vacuum leak (which those motors are known to have even in their car counterparts) or an idle air control valve that is sticking. Depending on which it may be. A little more info such as if it does it when you start up or only after it warms up will be helpful to diagnose. Hope this helps.

2006 Buick Rendezvous labors when n park & o in idle. Slight vibration & feels like engine is straining. Up running it seems fine, plenty of power.Fuel injectors or? Plugs good, wires new a year ago

Do you have a check engine light on? If so have you had the PCM fault codes read? It sounds like you have a misfire in one or more engine cylinders, and that is most noticeable at idle and in drive.

Don't worry about the fan. I think you have a bad temp sender unit. Replace that and see if it helps the stalling also. If not, go for an engine analysis. They will check for trouble codes and check engine sensor functions.

When ever i start to go from being parked my traction control comes on, only lasts for a few seconds. It happens on paved parkinglot, gravel. it doesnt happen all the time maybe once or twice for a couple...

Did you have "diagnostics" performed, or did you just have somebody pull OBD codes from your engine computer? Trust me, there is a BIG difference! Most traction control fault codes will not show up on a generic OBD scan tool. You need to scan your Antilock Brake System (ABS) module as well as perform a "vehicle-specific" scan on your Powertrain Control Module (PCM). (This cannot be done at your local parts store.)

There is also a Technical Service Bulletin (TSB) published by General Motors concerning intermittent traction control and other possible problems due to water getting into connector C305 and causing electrical short circuits. TSB Reference Number: 01-08-45-005E (Checking for this TSB SHOULD have been included in any attempt at a "diagnosis"). This TSB may or may not have any relation to your problem, but a thorough diagnostic check will verify this.

If this is happening when your tires are slipping on gravel in a paved parking lot, it may be perfectly normal operation. In this case, your traction control is only telling you that it is taking control of the wheel slip - especially if it happens when you are accelerating quickly.

We got the car a few months ago. Low tire pressure light came on during the first cold snap. One tire was couple lbs low. We reset it. Few days later the light came on again. Tires were fine. We reset it....

Hello: If the tires are programmed to the correct position on the truck the the tire that is showing low may have a bad sensor. The battery in the sensor only lasts so long (maintence item) When the light?message comes on is a tire actually low?

The oil system reminder needs to be reset so the computer knows you had the oil changed. The procedure is in the owners manual but can be tough to find so you might have to do a little searching for it. Many of the GM vehicles can be reset by turning the ignition key to "run" [but don't crank or start the engine] and then fully depressing and releasing the accellerator pedal smothly three times within 5 seconds. Turn the key off, wait about 10 seconds and restart the engine to see if the reset was successful. Check your manual first as not all GM's can be reset this way and yours may be different.
