Rear o2's will not affect the way the car runs and unless your convertors are clogged they should not be causing the problem.

I was getting a code saying it was a bad converter but I erased it and it never came back.

That code was p0420 catalyst system efficiency below threshold bank 1

Technicaly that code is saying your converter is not doing it's job well enough any more, but I doubt it is causing your drivability problem

Ok guess I'm lost again then. I'll just have to start throwing parts at it. All fuel pressures check out. Maf is good. Map readings are good. Coil and icm are good. Apparently the O2's are good.

What exactly are your symptoms? Is it just at idle?

 

[30thZ]

No never at idle. The car runs and drives awesome. Just every so often its like it wants to cut out and die. I'm talking like once every 20 mins of driving. Then ill let it recover and it will run perfect again. Then a lil while down the road it wants to cut out again. Very random times.

I hate to say it but that could be a symptom of a bad opti.
How are your plugs and wires?

 

[30thZ]

Wires are brand new msd and plugs are brand new ngk iridiums

 

[30thZ]

Is there a way to check the opti

Not sure if you are familiar with this site. This is shoe box's site. Lot of good info on there, although there are some changes in the 96-97 LT1's.

Another suggestion i would give is to invest in a FSM (Factory Service Manual) you can find them on ebay for around 50 bucks!

Opti's can be hard to pin down as the problem when they are not failing bad enough to trip a code.
I drove mine for about two years with an intermittant idle stumble that would only show up after sitting in traffic in the summer.
It finally got bad enough to set a code this year.
