Sorry no MN meet.

I was fine for almost 2 days after resetting the computer, but on my way home today the car died twice with no warning. Once when braking on a downwards hill for a red light, another when braking for a slight uphill stoplight. Seems electrical...no sputtering, jolts, warnings, just *ding ding* "Check Gauges"...uhg, engine is off.

No SES light when it did this...maybe a code was still stored. Will go to dealer on Monday to have them check for codes.

I still think your Chip has something to do with it. Swap it back if you still have the old one. Right now i think performance is second to driveablility.

I've been driving with the Superchip for longer than I can remember (last November?) with nothing like this problem ever occuring, but I will take that into consideration.

You shoulda been there today Mach!!!! :P

Mach, that was the same thing that would happen when my crank sensor was going.

Holy crap it just got worse! On my way to a friends house the speedo went nuts, lighting dimmed on and off, and finally she died when taking a turn...let me tell you its HARD to turn a Bonneville without power steering. Anyway I tried to start it back up...nope...after 15 seconds she fired up though. SES came on, so now I can get her scanned. YAY!

Ok update! Everyone gather around the fire...

Codes from dealer scan:
P0321 -- spark reference
P1361 -- ignition control circuit

They suggest I take off the MSD coils and replace them with the stock ones because maybe one of the MSD crapped out...coils do that. So that I shall replace them. If it still does it, then I bring it back in and it could be the ignition itself is going to hell.

What do you all think? I'm still gonna swap out the coils today though.

Forget the coils. You lost your crank sensor.

You seem sure about that Bill. Spark reference and ignition control circuit doesnt seem to be crank sensor.

Anyway, I'm still gonna do what they say THEN suggest the crank sensor because this is the dealer my dad has gone to for longer than I can remember, and a 20 year old kid coming in saying like he knows everything would not help out.

My car was doing what yours was doing really bad, and occasionally still does. I just gave it a good tune up and it helped it, but occasionally it will start to die or die at stops or when I am accelerating at higher speeds 50-70. My car also shudders slightly while at idle. When I get bad gas the condition is really noticeable.

Although I ran the codes and got low air temperatore on my MAT sensor and TCC problem I still think my problem has something to do with my coils. If one of the coils wasn't firing right it could cause my TCC problem, I think, by missing during a critical time (during disengage) while slowing down, thus causing the TCC to not disengage properly.

I was supposed to have diagnostics ran at a NAPA store but there idea of diagnostic was to just tell me what codes are stored in my computer. Here and I thought I was going to pay them $40 bucks to test compression, coil packs, and my ecm, among other things.
