Hi guys I have a r33 gtst with loads of mods injectors power fc exhaust turbo etc I have a probly with idle it hunts up and down ?? Also there is a sensor on the inlet side at the front of the engine that clicks like a relay when I disconnect and reconnect the tps I removed this sensor and it goes into the engine near the timin cover without this connected it idles fine but stalls after high revs any info would be great Thanx in advance
