I recently had a run on with some bad gas. I ended up having to replace the fuel pump, filter, injectors, and clealed out the inject pretty thuroughly. Before I drained the gas, my car wouldn't start at all, but after new gas was put it my car starts, however it idels very poorly, and I have unburned fuel in my exhaust, TONS!!!! I have recently adjusted the valves, and replaced the head gasket, put in new sparkplugs, wires, and coil packs, and crankshaft position sensor 2 months before this, along with an oil change. I have no idea what to do about this, and I really need my car to get back and forth to school. Please help me out.

This may or may not help. The vacuum lines in the top should be checked for cracks or breaks or if they are coming loose. In the 1993 models they control the oil pressure sensor and may be part of your idling issues.

Hi this may help u. Check to see if you may have wipped out the o2 sensors if u are saying that it is running poorly if they are not reading right it will be dumping raw fuel into the converter and causing the converter to glow red. But this may also be caused by the pcm computer may not be reading right also. I hope this will help you in anyway.
