Didn't get the chance to tear into it today. Wound up taking a ride instead. However, today it's a little better. Now it's only breaking up under/around 1500 rpm. Not really backfiring anymore either.
But yeah, still no codes. It seems to be slowly clearing itself up but who knows if it'll go away completely and either way it would be nice to figure it out so I don't have to fear driving the car in the rain
Somene on ltxtech asked if my air filter got wet. I do have a cold air intake that has a cone filter down low in front of the tire. He said his does sometimes and screws up his maf. But, I'm not throwing any codes. I would imagine I'd have a code if it were O2's. I know my caprice did when the o2's went bad. So aggravating.

I'm gonna clean the injectors and maf and put a new fuel filter in. If that doesn't help aeromotive fuel pressure regulator time.

I dunno if a wet air filter could cause it or not, but since we're on that topic how big is the filter on your CAI? When I got my car it had a Moroso CAI on it, and it had a K&N cone filter on it that was so long it almost touched the splash panel. I replaced that with one that was a few inches shorter, which I found after some research was the same size as the one the kit came with. I just wanted a few inches of insurance in case I ever hit one of those sneaky puddles that looks 2" deep but it's 12" deep.

as much as I hate to admit it (and I do) The LT1 is a great engine that is hampered by a unreliable ignition system. Chances are it is a coil or opti but I would do the LSX ignition upgrade way before I tried to do an LSX swap on an LT1 car.

It's a smaller cone type. Cheapy from autozone k&n knockoff. But, the splas shield under it was cut away by a previous owner. I'm assuming to get more cold air to it.

Honestly, if I do get rid of the opti I'm leaning towards a conventional distributor and a megasquirt ecu. Probably cost less than half as much as the efi connections stuff. Unless I decide to try and work a deal with someone who may be selling their set up

Do you remember Rob's setup from new england dyno on the white 96ss?? That was a nice setup and very clean. He is still on Nems if you have ?'s I am sure he would answer them.
