I can put it in neutral and start it. But when I force it close to park I can shut it off. It will start rolling away when on a incline.

Hestation rough idle for 5 to 10 seconds. Eventally check engine says o2 are reporting a Lean condition. Replaced pump and regulater. Smoked the intake with no leaks found fuel pressure at idle is 52lbs. Swapped out a maf sensed from junkyard still same thing. Replaced both up stream 02's still no change. Driving me crazy. Lol
The engine still runs but nothing else electrical works, everything shuts down. Everything. If I accelerate at less than 2800-3000 no problems.
First gear shifts hard when cold.
Sometimes engine turns hard (like early timing) sometimes turns fine and won't start, but stop cranking and then start cranking again it fires right up and runs fine. Any clues to these exciting challenges anyone?
How do you reset the brain on a 2000 GMC Sonoma
My truck has a 4.3 engine ,when I start it and let it run for about a minute then put it in drive ,it runs fine but, if you start it and immediately put it in drive it will try to die at cold or normal operating temperature. Then when you are driving it, it runs and drives fine until you start pushing it to go faster, like when you are in a hurry and then it starts spitting and sputtering and you lose power like its going to die.
