That should throw a code right.

Yes but it might take a couple of days. If you have time pull out some plugs and see if some of them have carbon build up on them

Yes, idk how many O2 sensors you have but if there is one on each side of the motor the side with the bad sensor will all be black

I'll have to check. I think I have 4 o2 censors. 2 before and 2 after.

Drove her home with no issues. Not sure what was wrong with it but seemed fine on the way home. Will prolly clean the TB and MAF sensor. Might change plugs as well. It's got champions. I'd rather had delco

Honestly I would just run some injector cleaner through it and see if it happens again

Yeah. What would you recommend. I have STP, Seafoam, and gumout at the house.
