The vehicle while in gear and hesitation occurs while driving and idle. And check engine light flashes also when the vehicle is in park these problems still occur. But the rpm is still normal. I have replaced the entire spark system. The ets light is on next to flashing check engine light.

Rough at low speeds
Chevrolet Cavalier 1996 ls 106000 miles
Fuel injectors were leaking. Replaced. O-ring split on install (without knowing). Gas filled (gallons) exhaust system. Fuel was leaking everywhere, blasting out tail pipe, blew a bunch of carbon out. Replaced o-rings. Changed spark plugs. Changed oil filter, replaced oil. Still ran rough. Fan was kicking on when it shouldn't (54 degrees out). Thermostat froze, replaced thermostat. Flushed radiator, replaced coolant. Rough start, once running it runs smooth on the freeway, no missing or anything. Starting scares the crap out of me. Check engine light comes on. It's throwing a code saying fuel to rich (or something like that). Planning on replacing the oxygen sensor. Any other ideas?
