Took off the Rotofab, cleaned the outer TB then started the car so I could open the butterfly to clean the inside. After a couple seconds of trying to open the butterfly, car stalled. Tried to restart the car and a no go.
Put the Rotofab back on, plugged everything back in, car started and runs fine but now I have a check engine light. Any thoughts?

Thanks

I'm running Livernois, probably to late to have anyone run my codes.

You cannot try to open tb while running. It will set codes. Sometimes it even ruins the tb. I have replaced several from customers trying to do their own tb cleaning. Engine must be off and key off. Hopefully you didn't make junk. Try disconnecting battery cables for a while. It didn't go into Limp mode did it?

Ok, I went out and disconnected the negative cable from the battery. Let it sit for awhile and see what happens.
Not sure what "limp" mode is but when I turn the key on (not start), it goes through that 100% complete check thing and then starts fine, seems to idle fine, just giving me the check engine light.

What should I look for to see if I ruined the TB?

I just disconnected the negative cable, will let it sit for 30 min and then go reconnect and start to see if I still get the engine light.

I'll take it out and run it for a couple of minutes, anything to check for?

The TB will reset and run a relearn procedure at ignition turn on (no engine running). It takes about 30 sec to do a run through. But it will *not* initiate this self test *if* there is a fault assigned against it (along with the mil light). There are a batch of fault codes listed that would prevent this from happening.
You will just have to verify *what* fault code or codes are logged in the ECM. Then clear them, at which time the TB should start its relearn function as above. It could take 2 or 3 attempts at this (fine tuning itself). Plus driving and letting it go into coast down also allows for added retuning the TB.

Do I have to get my fault codes read and cleared at "Autozone" or am I able to read/clear them on my own on the cars computer?

Very bad idea. You realize that will make the engine go WOT. With key off, you can still manually move the throttle blade.

Thanks for the replies everyone. I unplugged the battery last night, plugged back in this morning and started the car with no check engine light. Drove the 15min to work w/ no problems and no light. At lunch today, I'll take it out and get on it a little bit to make sure it runs ok at WOT.
Lesson learned!
