Trouble Starting, High Idle, Can't go to work...
It's fairly cold here, so I let it warm up to operating temperature for about 10 minutes.. it bounces around 1,500-1,700 rpms, and if I rev it, to say 3,500, it will stay there and slowly fall down to 1.5-1.7
Anyone had this happen before? what did you have to replace? I am very weary of shops in this town that are probably used to taking advantage of college kids who don't know jack about cars.
the car is driveable, but not friendly, I have to stand on the brake to keep it from taking off.
any help would be appriciated, I'm paying my way through school and I have to go to work...
edit: it is NOT throwing codes, or I would have already checked it.Last edited by justinmc978; 12-27-2010 at 03:28 PM.

Why are you idling your car for 10 minutes before leaving? Try getting in it and just driving.

Have you checked your coolant sensor? When mine was messed up it was revving all over the place but it did throw a code. It may not be you're problem but it's worth a look.

Im definately thinking its the TB bypass since it sounds like your TB is sticking a little.

^^^+1. The best way to warm up a car is to drive moderately the first 10 -15 minutes. If it is really cold, maybe let it idle for 30 seconds or so, then go.
TB bypass? I guess that could cause a problem, the OE design is to not allow TB icing under severe cold conditions. We bypass that so our TB doesn't heat up, resulting in a somewhat cooler intake air charge.
OP, glad it was a simple fix!

BS! In (-) temps oil can be like jello driving it is last thing you should ever do.. Guess you don't like you cylinder walls and bearings much eh.. I idle ALL of my cars till @ least some temperature shows on the guage.. Been doing it for 20 years on over 30 cars/trucks I've owned. Driving it when it's ice cold is dumb.. You guys can do as you like..

The only thing i ever heard about needs to be driven to warm up, were dirtbikes. I use to race motocross and everyone would ride their bike around mellowly until they warmed up to operating temp. The reason was because if you tried idling and letting them warm up that way, there would be no airflow going through the radiators to cool the motor off, so if you idled for about 10 minutes it would start smoking and your header pipe would turn really red. On cars though, you dont really have to drive it to warm it up considering car motors have a much better coolant system and we also have fans. Like smittro said, if im in a hurry i let it atleast get a little over 100 before i start going and i never rev it over 3k without it being close or at op temp.
