Alright, I just replaced my FPR and then my battery died (it was old), and the engine flooded. Anyway, I just put in new plugs along with WD-40 and ATF and it started right up.

Under no load I hear a squealing noise between 2000-3000 rpm when I rev the engine. It also is having trouble idleing, drops to 500 and almost quits then goes back to 1000. If I rev it up and let off the gas it will stall.

I also noticed that my a/f gauge is not lighting up at all. Do any of the important sensors on the UIM share a common ground or plug with the a/f sensor that could have come undone while I was taking it off/putting it back on? The engine threw out codes:

11 - intake air thermosensor
12 - throttle sensor - full range
18 - throttle sensor - narrow range
23 - fuel thermosensor

But, I had the ignition on while the UIM was off checking for fuel leaks. I reset the ECU and the codes haven't come back.

If the codes haven't come back then I wouldn't worry about it. As for your O2 meter just make sure that its grounded very well. Make sure to have the uim grounded (there is a stock ground on the passengers side fire wall, check to make sure you reattached it). The squeeling I can't help you with unless I heard it. You might want to check your belts to see if they are too loose. Hope that answers your questions.

NOP for this is to double check everthing you touched.

Most of these types of problems are caused by the person doing the work incorrectly.
