i just dropped a 98 gsr into a 96 civic hatch....i had to wire the usuall wires. ok now when i take off in 1st gear or reverse real slow (barely on the throttle) the engine revs up and down...does anyone know what it could be??? i switched the tps and map and its not that....any help needed.
thanks

 

IACV possibly??

 

Go over your VAC lines, and check your IAC with a voltmeter
