I have a 96 Saturn SL2, dual cam 160k miles It's been running great untill 3 days ago, now on a cold start, the engine sputters, untill it gets up to RPM, then runs smooth, on a hot start, it sputters, then dies, the only way to get it to start is to hold accelerator down then it starts rough untill it gains RPM. Then runs smooth, I've noticed a strong exhaust smell now, and black soot coming out of the tail pipe. If I push the accelerator fast, the engine chokes. It has all new injectors, plugs, plug wires, and fuel filter. There was also black soot, on the plugs. I've also noticed a slight ping in the engine, that comes and goes. Although, I'm not sure if it's just the muffler rattling.
The past few day, it's seemed to get a little worse.
Any advise would be greatly appreciated.
