well my car has had a surge since i bought it so i set minimum idle and cleaned and adjusted iac and it still has a surge im thinking i should adjust tps since its the only thing i havent done. But i dont kno what to use as a jumper wire to connect the connector and sensor together also i dont get how something that is bolted on volts could change. also i noticed when driving my car the voltage surges too and when my voltage goes down so does my idle then the voltage goes back up and so does my idle.

 

tps was set at .60 volts now its back to .54 volts still surges i guess the next step is the voltage regulator.
