Check engine light after cleaning throttle body?
I did a tune up on my car. I changed the spark plugs, replaced the air filter, cleaned the MAF sensor, and cleaned the throttle body.
Everything went fine until towards the end of the throttle body cleaning when the check engine light came on. The weird thing about cleaning the throttle body was that the engine would shut off when you unplugged the rubber intake tubes to get to it. We sprayed the cleaner in, reconnected the tube, turned the engine on, reved it a bit, then shut it off and repeat. The engine shut off a few times though when lifting the tubes. Also, we managed to lift the tube just a little while the engine ran to get the nozzle in and spray the cleaner. The engine would idle roughly and then idle strong, my dad said that's normal as it was burning the cleaner.
Anyways, close to the end of using 2/3rd of the bottle, the check engine light came on. We finished cleaning, reconnected everything the way it was, and the light was still on.
We disconnected the battery and reset the computer, and the light went away. Hopefully it doesn't come back.
My question is, is there anything that we could of messed up while cleaning the throttle bodies? If the engine chugged and shut off would that be the reason the light came on and stayed on even after everything was reconnected?
I just want to make sure we didn't F anything up...
