Checked everything and all connections look good, tight and clean. Precise1: It is a manual. It actually is the same color as the one in your picture! I will start looking for vacuum leaks next. I'll look around for a spare ECU as well.

Thanks for the suggestions, guys! I cleaned the connectors with emery board and blue shower during installation, so that's good. Will try the fuel system cleaner and check the wiring further down the line, and check the air filter, etc.

I'm stumped folks. I've had my 95 since 2000 and love it. Check Engine Light comes on - ECU clearly reports 33(O2 Sensor) and 43(Throttle Position Sensor). Replace both, performance is restored and Pathy drives great. Reset ECU. As soon as you start driving CEL comes back on and stays on. ECU still reports 33 and 43. Even tried unplugging battery for 36 hours, no luck. Any ideas/suggestions ?
