searched but no luck. I recently did a 5spd swap on my 98 ls, now i'm using a 95 p75 ecu with the conversion harness, when the motor is cold the idle surges for a couple of minutes, there is a sensor on top of the intake that i had to unplug so the car will run. Now there is a vaccum line running from that sensor that goes to the charcoal canister, is there any other sensor that i have to unplug to stop the surging? There are no check engine lights anymore since the conversion to obd1.
