Hey everyone, This weekend I finally got my car running right with no CEL. Changed out my O2 sensor, which was causing my code. I also fiddled with my cam gears a little bit, backed the exhaust gear to -1 and took the intake from 2 advanced to 4 advanced. So, driving to work this morning, I had a problem where, in 4th or 5th gears, if I was pushing on the gas pedal a little, it felt like the engine was bogging. Then, if I stomped it real hard, the engine felt like it went right back to full power. It mostly happened in 4th, but happened a couple of times in 3rd and 5th. My distributor is timed off my exhaust cam. I didn't check my ignition timing since I'm too poor to own a gun right now. The plugs are almost new, as are the plug wires and the distributor parts. My only thoughts are that the throttle plate may be sticking, my injectors/plugs may be clogged/fouled because I was running so rich without the O2 sensor, or that my ignition timing is off. Like I said, I only advanced my exhaust 1 degree, which shouldn't cause me too many problems since I was running the stock 18 degrees advanced before messing with my gears. Thoughts? Comments? Thanks in advance.
