2000 Sonoma, 2.2L Auto, 2WD, 85,000 miles.
Driving along, all is good. Stop at a light, foot on the brake. Light goes green, take my foot off the brake and hit the gas (gently, I drive like an old lady) and the truck starts spitting and sputtering, making that hollow sound like the throttle blade is open, but no air is moving, truck is barely moving. More gas makes it worse, bogging, tach dropping down to around 500 RPM, voltage guage drops, oil pressure starts falling, lights dim. CEL never came on. I dropped the gear selector down into "1" and ran it back through the gears back to "OD", nothing changed. Stopped, put it in reverse, and backed up a lil bit, put it back in drive. No change. I did these things thinking maybe it was stuck in OD and this would move things and help. Went 500 feet and it returned back to normal. Went two blocks and it did it again. Parked, turned it off, and restarted, same deal.
Last night was the second time it did this. First time was on a clear and dry winter day (six or seven months ago), so I don't think the rain had anything to do with anything.
Runs and drives fine this morning.
Anybody got any thoughts? Something sticking in the trans? Fuel pump? I'm gonna see if I can get my hands on a scanner tonight and see if the computer can tell me anything, But like I said, no CEL during this. CEL is there during startup bulb check. Truck has been driven gently it's whole life. Still has OEM plugs and wires that will be getting replaced this week. Had a CEL a year or so ago for the airpump, I never fixed it and the light when away.
The only issue (other than a few batteries and brakes) with the truck since new was a trans line went bad and I think it got ran dry at ~25,000 miles. Don't know if they just replaced the line, and refilled it, or if they rebuilt the trans, too.
Thanks in advance,
