: a bunch of problems

I have a 99 Deville. Everytime i drive this car, I find something new. I did some searches and found my sway bar thing might be loose. But that's not my problem. I'm in NYC and recently it snowed. Snows gone but it left me with some problems. My traction control is overly precautious now. I had a traction control light. I cleared it, never came back. After that though, every time I leave a light, my traction control engages for a couple seconds. Pisses me off. And on top of that, everytime I'm at idle or turn off the car, I hear bubbles coming from under the dash, probably from heater coil. I checked though and the coil isn't leaking. I got air in the coolant system somehow. I did the headgasket leaking check when you take off the coolant cap and check for bubbles. No bubbles. I think I may have a leak somewhere though because I had to add coolant 2 weeks ago. How do I get these bubbles out of my coolant system. It sounds like an aquarium.

The engine is designed to purge itself of air in the cooling system. Check the purge line to be sure it is clear and flowing.

If the purge line is clear have a coolant byproduct (exhaust gas) test done at a radiator shop.

If it passes that you can do the normal diagnostics.

If it fails that you save a lot of time, you'll know it's head gaskets.

Thanks for the replies! Anyone know why my traction control engages at every light on dry pavement?

Maybe a bad wheel speed sensor. Any codes?

The first thing I did was check for codes. No codes. It baffles me.

Maybe badly matched tire sizes or a low tire.

My '99 used to engage T/C very often when pulling away from a stop in wet and damp weather - it was a faulty wheel speed sensor. Never bothered to repair it. It didn't do it in dry weather though, so that sounds a bit of a puzzler...

Yea this thing irritates me. i stopped driving it and drive my impala now. i hate my impala but it doesn't have any problems because it's brand new. Got it for the wife. Shoulda bought another cadillac. But I checked codes again and no codes. It still engages the TC. It makes a bad clicking sound like something is rubbing and then the DIC says traction engaged. I checked tires, they are fine. I'm stumped.
