recently replaced the frps sensor. and i was cleaning out the cylenders because it loaded up with gas. i disconnected all the coil packs except for one ( i looked away, thought i took them all off, and forgot one). had my buddy turn my car over so i can see the fuel come out and boom. Small fire on passenger side. Didnt do much but burned 3 vacuum lines which i replaced already, and left a little burn mark on the top of the coil pack.... Anyway, i ordered new NGK tr6 plugs from lethal, and installed them after gapping them to .035. WHen i drive her down the road and i put my foot in the gas, not to go fast, just to get up to speed. She cuts up badly. I have the p1131 code "lack of Upstream Heated Oxygen Sensor Switch - Sensor Indicates Lean - Bank No.1" which i know means my front 02 is bad. but would that cause my car to cut up like that?

just incase this helps, i will disclose my mod list incase it helps determine the solution

stage 5 ported blower
2.93 upper
4lb lower

It certainly can. The bad 02 is making the AFR go haywire which in turn makes the ECU bug, causing your cut.
