I put a 98 jdm b18b in a 2000 civic dx and I'm running a obd1 ecu...the tps that came with the engine was craked! The result was an o.k. idle at 800rpms but some time my engine light would come on and the rpm would fluctuate between 700 and 300rpm and would stop running if I didn't give it gas! I was able to grab a jdm tps off of a b18c and know I can't get my rpm below 1100 and if use the car it goes up to 1400rpm and I stil get error code 7= TPS cause the light is always on

Need help and yes I have played with the tps position

Thanks!!!
