#35 of 68 Buick Rendezvous Idling issues.
Apr 27, 2011 (6:04 am)
I have a Buick Rendezvous 2003. I couple of weeks the car started to idle. My wife told me about it a couple of weeks ago, but I did not believe her till a felt the problem myself.
I was driving home and suddenly the card was idling high in the 2500 and 3000 rpm when should be in 2000 rpm. I took foot of the accelerator and the car was going and increasing the acceleration. Luckily I was home with the car at this point. I park the car with the idling high, then I put it in park the car started to increase the rpm up to 5000 rpm, when I decided to shut it off. I waited a minute then turn the car on and it was working fine for about a minute then it started to idle between 1500 and 2000 rpm.
It had a whizzing noise. I took it to a mechanic and replaced the booster the whizzing went away. There was a leak in the booster changer.
Today I was driving the car and I was noticing that the rpm are still oscillating when the car is parked.
I donít know what it could be. I just donít want to drive this car and start happening what happen to the Toyota cars.
Any ideas what it could be?

I have had that on my Pontiac version (twice so far). My mechanic suggested sticky throttle cable but blipping the gas pedal doesn't seem to help. Shutting off and restarting does seem to resovle it so it would tend to make me think about some electronic dodad (Idle air control?, Throttle position sensor?). Please let us know if you get an answer because it can be quite annoying.

It was the throttle position sensor. I had taken it into a Ford dealer of all places and they new right away when it had stumped everyone else. I think it's been a month or two now with no issues. The only thing I've noticed is once in a while it does "over crank" when starting every now and then but no stalling at all.

My 2003 rendezvous is having the same problem. My intake had a crack in it and got that replaced along with everything else that helps it.
Were you able to get it fixed? What was the cause of the problem?

Hold key in Start position, light switch on auto, lights dim like they do if you try to start in gear
Still in start, every 7 seconds a relay clicks and the dash lights flash
Still in start, drop the jack hard and the car begins to crank & starts (repeated 3 times)

I have a 2004 Rendezvous, I detected a strong smell of gas and thought some must have spilled or maybe the cap wasn't on tight. That night driving home from work I still smelled gas and noticed the gauge was on E and fluctuating when I got home I called a mechanic and made an appt. for the next day. Monday I tried to start the car but it didn't want to start, it made me a little Leary to drive even if it would start so I had it towed. Gas rolled out from the back of the car to the front and left a pool.
The mechanic found the lines all rotted and was told the parts are a national backorded item. I have been online and on the phone with Buick then GM since then it is now next Monday. GM customer service is sending documentation on to a "higher dept. in my district and I will hear from them in 1-2 business days! This is crazy!
#44 of 68 2003 Buick Rendezvous No Crank/No Start
Oct 17, 2011 (6:46 am)
I am at my whit's end. My Buick started randomly not-starting and now it has become more-so the norm than the exception. Sometimes it will start after about ten seconds and it has been up to 3 weeks before it will crank. Here is what is happening: When you put the key in the ignition cylinder, it recognizes the key, but when you turn the key, the guages bottom out and the lights dim like it is starting but the starter does not engage. You can hear relays click but those are the only signs of life. I originally thought it was the starter and replaced it but still have the problem. I don't want to take it to a mechanic and have them throw darts at the problem. Does anybody have an idea of what this is? I thought it was the PK3 but after installing a bypass, the problem persisted. Another thing is that ocassionally, the doors do not unlock when you put the transmission into park. Other times it will. I can change gears without applying the brake as well. Any help is greatly appreciated!!!
