Hey guys, my friend has an lt1 and 4l60e combo in his camaro, it has a miss to it, not super bad but bad enough. when he cruises at half throttle or less it runs fine and pulls fine but when he floors it it doesnt want to run over 4k and starts banging out bad. would whatsever causing the miss be the problem? he was told the cap and rotor are really old and bad. thx in advance guys.

 

I hear the opti spark is a royal POS. I would look into that first. Either way its ignition or fuel related issue.

 

I have almost no experience with lt1s, but i dont think they have a "distributor", they have a weird setup called optispark. Ive heard that optispark is junk, but ive heard also that its very good. Alot of people have told me that the optispark got a bad reputation due to water soaking in, that was the 93 model. It was suposedly fixed in 94' and up.

None of this is fact and only hearsay, ive never really touched an lt1 before.

 

ive had two others but never experienced this problem, should i post this in the ltx section?

 

No, put it on the brake board and see how far you get.

 

yea maybe next time
