So, I was on my way to work this evening, had my heat on and blower motor on 3. The Power Loss light popped on a couple times, and the volt gauge was at maybe 15 volts. The car didn't run poorly and the gauge settled so I didn't think much of it.
About 20 miles later, I got hot so I turned my blower motor off. At this point, the gauge went up and down and up and down. The Power Loss light stayed on, and the car started popping and backfiring. The thing sounded like gun shots. I hit my 4 ways and call my coworker who was about a mile behind me. I kept chugging along and the gauge was going haywire and would swing up to 15-16volt and drop, and back up and down. I noticed that every time the 4 ways flashed, the engine would pop. I turned the blower motor back on to 3 and it ran fine the rest of the way to work.
Just for a wee bit of backround, in the hurricain, the rain came in and drenched my stage 2 LM. A pin broke off of the LM so I pulled the pin out of the connector, pulled out the broken pin and put a stock LM in. The pin that broke was the regulator signal wire on the LM. I doubt it had anything to do with it.
I haven't been able to pull codes yet as I'm at work, but to me its sounding like a power module. Does this sound right?
