Car won't idle.
 

I changed the alternator yesterday I broke the wire on top I soldered it back together everything was fine. Idk if that's related.

I went to start my car this morning it won't idle. And I'm
Not throwing any codes. Fuel pump primes too. I also cleaned the MAF it was dirty. I did slightly brush against the wires but not on purpose.

why did you change alternator, check your battery, I had a battery that still started the car, but wouldnot run for nothing, new battery and car ran normal.

Squealing pulley. I have the lifetime warranty so I said what the hell. The car ran great before the alt swap I did notice it wasn't charging after then I found the brole wire. Could I have drained th battery too much driving without the alt charging it?

Could this be my problem?
