Hope the pcm ends up being your resolution. ..electrical gremlins are bastards

Yes they are. Engine runs great otherwise, still have a knock count issue pulling timing here and there but I know it the rockers.

Have you ever checked cylinder pressure? What octane gas and how much timing?

No, I havent. Running fresh 93 with a CR of around 11.5/1 and the log is showing around 30 degrees advanced.

I'm getting knock counts at idle and can hear the rocker chattering as the counts increase.

Im not counting it tackled yet but without the members of this site..It would have a LS in it. lol

That's more than likely your problem... I would zero the tables out and go at it... 30* on 93 and 11.5 ain't gonna knock... you should pull a few plugs and check cylinder pressure. .. static compression don't mean a whole lot... we get almost 190 psi out of a cast iron headed 9.1:1 Olds motor. .. has a ton to do with the ring package and cam...I zeroed out my tables. . Ain't gonna hurt you're no where near the edge

I received the new computer from firebird_1995. Fired up and sounded healthier. Let it warm up and do it's thing. Idle was steady and not erratic. Took it for a drive and this thing pulls hard. I have the factory tires on for now and it just obliterates them with a blip of the throttle. I can finally say it's ready to be tagged. I did take it into the outskirts of Dover to get a full tank of gas and to grab dinner. She may look like she's past her day but she made some heads snap.

Well I took it through inspection this morning and it ...Failed. I kinda figured it would cause on the way there I had a real bad stumble at low RPM and popped code 64. I had an issue the other day while doing a log with the R bank O2 randomly dropping to .4mv. Well today it failed completely and is running pig rich. After some research I found that Bosch O2's suck in our cars. I've used Bosch for years and always trusted them but anyway...No one in Dover has ACdelco's at a reasonable cost so I have 2 new sensors getting 2 day shipped to me.

I'm going to go on a little rant but the DMV "technicians" are absolutely fucking retarded. This guy looks under the driver side of the car and say "You don't have a Cat"...I proceed to tell him its on the passenger side of the car and you wont see it by using the little mirror looking under the drivers fender. He then goes to his little computer and and says it failed cause it doesn't have cat. I got pissed and told him "It's a 94 it only had 1 to begin with and it's fucking right there"...wtf. Luckly, one the the older guys comes up to this clueless motherf^^^^r and told him I was right. Still failed but at least 1 guy showed up to work knowing his job.
