I did an oil change today followed with the installation of my A/F guage. When I started my car the car could not hold its idle and died. I would have to sit in the car with my foot on the gas and wait until the car warms up before it would not die. And even then the idle is very "bouncy", between 500rpm and 600rpm. The car was idling fine before today. What happen? Any help would be greatly appreciated, thanks .

Info on my car:

91 TII, stock.

Sounds like a bad vacuum leak. You probably bumped a vacuum hose somewhere and it cracked. Go buy some carb cleaner and spray it around your engine bay as the car idles and listen for a tone change. When you hear it, there's your leak

Most of all: don't worry! Your engine's not blown.

Anything else that could be wrong?

Well, yeah, but I don't think they're too likely. The BAC or ABSV could have gotten stuck, your TPS could be shot, your AFM could be partially disconnected, the gods could hate you.

Check for vacuum leaks first, though Oh, and make a sacrifice to the Rotary Gods, just in case.

Since you were probably in the area of your O2 sensor, i'd check the TID (Turbo Inlet Duct-Goes from the front of the turbo to the airbox/filter) If it's stock, its probably really hard near the turbo...

it is a vac leak I did the same thing when I had to take off the manifold. I missed two or three vac lines when I reconnected them it worked fine.

Which hoses were they? I was talking about my intake/air filter.

When you say spray the carb cleaner do mean spray it on the vacuum lines themselves or what? Please advise on the best way to do this test.
My car seems to idle low on warm days and on cold days it idles perfect.
Does this indicate anything?

Thanks
