I have a really bad exaust leak, ive got valvetrain noise or a little bit of lifter noise. This is causeing massive spark retard. I know cause i tightened up alot of the exaust and it felt WAY more powerful after that. I know the damn module is sending spark knock. Where can i get an lt4 knock module, or how can i just eliminate the damn thing all together. thanks ;]

 

GM part # 16214681

$31.02 from www.gmpartsdirect.com

 

"LT193" has a 1993.... the LT4 KM does not work with the 93's.... there's no place to plug it in.

Fix the exhaust leaks.... they will screw the A/F ratio up by messing with the O2 sensors.

 

oops, my bad

 

I would do a search of previous threads, this was brought up about a month ago. A guy with a 93 Formula had a similar problem.

 

Yeah i guess ill be fixen them, damn thing is REALLY annoying man lol.
