1995 Chevy Silverado V8 150,000 miles
Well, the last question I asked on here was a few months ago. I had some overheating and white smoke.. turns out it was a head gasket, after all. Well, you know what they say, if you're replacing the head gasket, you might as well replace everything else while you're in there. So, I ended up replacing all my gaskets and rebuilding the entire top half of my engine. Had to clean the milky oil out of everything, and what not. Well, my truck has been running great since. Until today...
You see, right before I had a head gasket blow I was at a stop light one night, and my truck just died. There was no indication what so ever that it was going to die. It didn't sputter, or jump. Nothing. I didn't think anything of it, because it didn't happen again. It started right back up without a problem. And this was a few months ago. For the first time since then, today my truck died while I had my turn signal on. Now, I don't know if this will help but when I turn my turn signal on my battery gauge flickers. It jumps back and forth. It's always done that.. never had a problem. But, It was flickering today when I had my turn signal on and my truck died, again. Again, it started right back up without a problem.
Any ideas what this could be..?
Much appreciated.

Chevy; Some dash voltmeters are more, let's say, 'sensitive' and will show fluctuations as you described. I'm not so sure that I'd be too concerned with that. But, the dying is obviously abnormal. The idle speed is controlled by the IAC (idle air control) motor. It is very common for those to get dirty/sticky over time. It is just an electrical solenoid that opens and closes to meter air flow which controls idle speed. If it starts right up after dying, I would suspect the IAC. 99% of the time, they can be cleaned and work just fine. Do you know what the engine speed is at idle? (do you have a tach?) It should be in the 600-700 rpm range in Drive. (or Neutral if std. trans.). If this is not the problem, you may want to check the fuel filter and fuel pressures.
