just did an obd0-obd1 conversion. after lots of kicking and screaming, there are no more check engine lights. BUT after about 2500rpm if hit full throttle the rpm goes nuts. it goes to up and down crazy. it does this at about anything over 50% plus throttle. i have NO idea what the hell is wrong with my car. can anyone shed some light PLEASE.

 

My car did the same thing when i reversed the plugs from my MAP and TPS. So I figure it has to be somewhere on the MAP or TPS.

Check for continuity between the plug on the sensor and the corresponding wire on the ecu plug.

It could also be possible that the harness was put together incorrectly and a wire might be switched

Just giving you pointers to start w/

 

Thanks, i totally forgot about the map sensor.
