Whats up guys? Here the low on my car. Hell I'm just trying to sell it, but I can't sell it like it is.

I got the car with a BHG and fixed it, no problems. Ran great for a few weeks, but check engine light was still on.

The car started doing this thing where it would hesitate, then the check engine light will actually turn itself off, then on, then off again, and by the time that little cycle is complete it will choke and puke if I try to give it gas. Even if I try to park it and let it idle, itll eventually die out. Thats if I even make it to a parking lot without dying on the road. Once its dead, it wont start up for a few hours. If I let it sit long enough, it'll go back to running fine on short trips (2 miles or less).

When the car does run, it gets bad gas mileage and smells like its running real rich. Also, the check engine light doesnt turn off. I've only replaced a few things, since I dont want to dump a whole lot of money guessing whats wrong.

I did do the cap, plugs, plug wires, alternator and battery to eliminate the charging/spark system. Timing is right on (+10ยบ TDC). I did the fuel and air filters. I also replaced that damn TFI which looked like it was going anyways. Recently I re-did both o2 sensors, and it seems to not be running rich anymore.

If I turn the car off, then try to turn it back on anytime within 5-10 minutes I get a real rough start also. If it sits a while, itll turn over fine.

Is this a common problem? The weather conditions vary, but I live in chicago so this has mostly happened in fall/winter temperatures and weather.

God I hope this isnt one of those posts where theres a million duplicates, but I need to get this bad boy running and this damn check engine light off. ODB1 sucks.

Thanks in advance all.
