What is your question?
Sometimes when I really need to get somewhere. Like work, or across the railroad tracks, or making a left hand turn. My 1994 Chevy Van G20 5.7L would stall out. Thankful the battery is new. It takes many starting turns for the engine to start, with a lot of dark smoke from the tail pipe, only to repeat when I put it in drive. when It does start I have to take off slowly to get out the way. Thinking this will continue it doesn't. the Van runs okay again, even up the steep 2 block run up the hill. Then when I reach the driveway it starts again. I replaced the usual suspects. No engine light is on. Checked vacuum hoses. Pass smog test. Sometime rough idle slightly with brakes applied in drive.
What makes this problem better or worse?
It often happens on city street, not on the highways or long trips.
How long has your 1994 Chevrolet G20 had this problem?
It did this before around 2010, then I replaced the ECM, under the distribitor cap 2010/2018, the Coil in 2008, 2018. the Map sensor 2011. Two months now after replacing water pump, heater and air condenser, radiator and transmission fluids and filter. spark plugs, wires, cap and rotor, ignition coil
