I was reading up on ground wire placement. I have a 99 Chevy Suburban k1500 5.7 l. When driving, it will cut out, gauges peg and engine
sputters...loss of power. At other times it drive with now problem. recently had the shop put 1k into it. New cap, wires, plugs, o2 sensor and it ran great for two weeks. All problems gone. then when driving in cold weather and using the 4x4 it started acting up again. I know that I have a bad 4x4 sitch and it comes in tomorrow...but it seems like there is an electrical issue. perhaps a bad ground somewhere. it is not the fuel pump as it was tested and it has a new ignition switch.
JA: Thanks. Can you give me any more details about your issue?
Customer: The trans isn't slipping. It has full pwer when it isn't acting up. Doesn't seem to have a pattern. yesterday it was at a stop and when accelerating from a stop it died suddenly. Then, 10 seconds later, we restarted it and limped it home. It idles fine....no problem, when parked. Revs fine in park. Problem is only when driving.
