Hey guys, My sisters Del Sol Recently started surging in idle (goes from 1000 rpm to 2500 back down to 1000 continuing the process) like a heartbeat we think it's the TPS (Throttle Position Sensor) but we cant find anywhere that carries them we checked the MAP sensor and it's good.

And does anyone know where the diagnostics plug is for a code reader? (we did the self diagnostics but would like a lil more info)Thanks guys.
