I have a 97 Chevy Express 1500 that's starting to act up. It starts strong in the morning and runs great at highway speeds (for the most part--read on), but if I stop and turn the van off for any reason, the second start requires a heavy foot on the gas and dies when I put it in gear. I basically have to rev the engine and pop it into gear to keep going. Also, I've had a few times where at highway speeds the engine seems to want to die. I tried to correlate this with running cruise control, max ac with highest fan speed, and a power inverter at the same time (because it seemed to do ok when I backed these off), but I'm not sure. The gauges show that the alternator is charging, but if I let the van sit for a week the battery is dead. I tested for parasitic drain using your resistor method and I only show 16 millivolts at rest. Finally, two years ago I had a power steering fluid leak that I repaired, but I wonder if fluid on that side of the engine got into any wiring. Love your videos and your clear, enthusiastic style!!! Thanks!
Update: I forgot to mention the one and only code that showed up was about the engine coolant temperature sensor. I replaced that last night and cleaned the air intake and mass air flow sensor. This morning I cleaned up the main battery ground, which didn't look awful but I sanded it up anyway. So far, I can start right up, idles very calmly, stays calm for as long as I want at idle, and restarts and runs smoothly without any problems. I'll be cleaning other ground wires and trying to get at the fuse panel when I have more time but so far so good. Thanks for the tip.
Thanks for the tip! I'll check it out.
This vehicle was known to have a corroded fuse panel give that a check especially underneath it and all grounds - any corrosion found clean or replace
