No it hasn't I am having trouble figuring out what is wrong with my camaro after awhile of driving it will bog down for a second then regain all power right away I replaced the coil,did an injectio clean,changed out my fuel filter,did a tune up,checked my moduel it was fine,did a fuel pressure check and it was good it has no vaccume leaks that I know about somebody told me to change out the rotor in the opti cause it might be lose any suggestions????

Sorta sounds like what mine is doing... Is the idle normal? any SES light/ trouble codes?

sounds about like mine also. It did that for about 2 weeks. Now its to the point where its hard to start, has alot of black smoke when reving, wont stay cranked, backfires when trying to keep it from dying, and just dies.

The cap and rotor are like any other distributor WEAR ITEMS but the ignorant folks of the LT1 community prefer to ignore it till it wears out them blame "bad design" and pretend the whole thing died instead of just a worn out cap and rotor.

The ses light does come on but no codes come up it says no saved codes

The Idle is fine for a while but it fells like it want to die out after a while

Mines doing something similar, I just replaced the plugs and wires, the fuel filter, the pump tool a dump, checked with a gauge, and it still has a miss, pulled one of the plug wires and tested the spark, it was yellow. I took off the coil, and tested it, it was about twice the resitance, replaced it and no change, so tomorrow I'm taking it to a mechanic to dignose it, I'm stumped and need the car yesterday, I really don't know what else it could be.

1994 interceptor

Did the mechanic find out what the problem is

1994 interceptor

Does anyone have anymore suggestions on what to try next

1994 interceptor

Does anyone think I should try the opti wireharness

lol id love to give some sort of good news, but im on optispark #4 and everything i have read in here are things i hoped and prayed for, but i hate to say it, but most likely just the opti, how many miles on the car?

1994lt1ta

oh and a couple more questions...the longer it idles the shittier it runs? and when you punch it and get it near redline does it backfire and fall on its face?

1994 interceptor

It just turned over to 140,000 and it does back fire when I punch it all the way down what does that meen

1994lt1ta

yea dude i read more of the things you said earlier in the post, and from what you told me, its def an optispark

1994 interceptor

Hey thanks man Thats kind of what I thought it was from every one telling me the same thing

If the check engine light comes on, there pretty much has to be a code registered. Are you retrieving codes soon after the light comes on? Some codes will go away after a predetermined number of key cycles that the trouble is not detected.

Any time the opti is suspected, the harness should be checked, too.

Your cap an rotor are shot. They should be replaced every 30,000 miles. At 140,000 miles replace the whole optispark.
