A friend of mine recently put a 125 shot on his 94 LT1 Roadmaster. Sometimes when he sprays it the service engine light will kick on and the tranny will shift way early if he's at WOT and also wont kick down into passing gear.

Another problem he's having when spraying it is the car starts spitting and sputtering really bad up around redline in 1st after he recently removed the MAF screen. I'm guessing he needs to put the screen back in lol. What would cause this after removing the screen?

 

I found the problem.
