First Question....

I just noticed that when I go out and start my car in the morning and/or after work it ildes kind of high 1500rpms.

If I drive for a bit, and shut the car off, turn it back on, it idles at around 1100rpms.

In the winter it used to idle sometimes at 2000 or 2500rpms when it was really cold, but I took it to the shop and they said they replaced a temp sensor and throttle position thing.

Any idea what could be going on there?


Second Question...

Last night I was out driving around with my friend with a Tiburon, his car looks fast (has the body kit and fancy paint job, but mine is normally way faster then him).

I normally kill him on the turns, but last night whenever I slowed down to take a sharpe turn, and then tried to accelerate out of the turn, my car rocked violently, almost like I had left my transmission back at the turn. It happened several times, and once it happend when we were at a red light (going straight). It was like it couldn't grab the right gear.

I've always noticed that the tranmission tends to "slip" during turns, it happens everytime I turn into my sub division, the engine revs a bit high like it can't catch a gear.

Any ideas?

Trans fluid was checked less then 2 months ago.... it'* ok.
My mechanic said there was no signs of tranmission problems in the fluid. (if that means anything)

And just to show you....

(again... I was having fun w/ the camera)

Just turned the engine on... the outside temp is about 27c.



And as you can see... she'* in park.

Yup..you're idle looks a little high...

try cleaning the IAC.
How many miles are on your car? It sounds like your clutches are slipping. :( It'* never a good sign either way though. you might want to take it easy on it. The transmissions on the earlier bonneville'* (even the newer ones too) are weak for how much torque the 3800 puts out.

My idle never drops below 1000rpm....
What is the IAC?
How can I check what the ECM is calling for?

Right. Most GM cars I drive, brand new and old, idle around 1000-1500 on a cold start. I think the computer is set up that way so that the car doesn't stall out when it is cold. After a few minutes the idle comes down to 750.

And a word about the tranny fluid - It should be changed out regularly - every 50,000 miles. If it is burnt then it is already too late. The level may be full but you should keep track of this. I'm not saying that this is your problem, though.

Ok, my idle problem seems to have gotten worse ... in the respect that now I can't take my foot off the pedal w/o the car stalling.

I had to drive to work with my foot on the gas at all times.
At stop lights I'd have to put her in neutral, one foot slightly on the gas and the other on the brake. Very odd driving style

I was wondering if any of the gurus had any ideas....
I'd also posted a more detailed message in the Performance forum... since I am having Performance issues.

Arg..... this is turning out to be an expensive summer car wise. I've already spent $500 (Cdn) in repairs, paint and upgrades to the car. Now I'm dealing with a possible bad tranny, a fault in the front wheel bearing or something, and now maybe something else.

yes, its a hard life. atleast all of your probems are hidden behind the beautious appearanc of the exterior. thats one hot car.

Thanks rjolly87 She is a nice looking car... just wish she performed as well as she looked. :(

Oh the life of a Bonneville owner.... all my time/effort and esp money goes into the car. I need new shirts/pants for the summer, but I'm skimping so I can afford to keep her running.

(Reminds me of a post/thread in the General Chat)

The boys over in the Performance forum think it'* a fuel delivery issue... so add another problem to my list.

I won't know for sure until my mechanic gets his hands on it, and that won't be until I've got enough money, or at least my next pay cheque.
