2002 Buick LeSabre Why does my buick idle so terribly?
Why does my buick idle so terribly?
What is your question?
My 02 buick les is running like crap. Catalytic converter cut off, throttle pos sensor just replaced, coil packs and module replaced, all recent. For starters, I drove my kids to the bus this morning and I wasn't even pressing the gas, it just went. It idles very rough. If it sits for a day straight, usually damp mornings, it won't start at all, just turns over. I have to turn the key and hit the gas for ten minutes before it will start (very rough) but it's the only way. It's like there's gas but no spark. Yesterday I stalled out at the kids school, pulled to the side, shut her off and turned her back on and it was fine. I can't afford a shop and would like to do everything myself. Tell me this is possible! Single mom just looking for a lead!

Always has been. I got the codes read yesterday and the tps is still there (wasn't cleared) and bank 1. Idk what that means, and the guy at autozone said it could be many things.
battery should have been disconnected when TPS was installed.that's why the code is still showing up,computer still thinks the old one is on it.could be a vacuum leak,iac valve dirty or bad,intake leak or many more things.
I had the exact same problem on my 1993 Buick Lesabre. I replaced everything I could find, all sensors, plugs, wires, vacuum hoses, coils and ignition module, etc and etc. I finally had to let the mechanic look at it. He put the brake on to shift into drive and found the problem right away. He heard air blowing when he depressed the brake. That told him the diaphragm in the brake booster was breeched, leaking air from the vacuum system that controls fuel flow making the car idle rough and stall often. Some days it ran fine but not many. Anyway, I spent $350 and replaced the booster and the car purrs like a kitten @ 240,000 miles and 24 years old!
