5.3 tps voltage high idle I have a 92 240sx with a 5.3 swap. im using ls1 accessories and intake and a manual transmission. Car was running fine last week, started it today and idle went straight to 3000 rpm. ive checked for vacuum leaks, MAF, MAP, IAC, and TPS are all working properly but im getting 11v to the 5v reference on the tps. If i unplug the tps it runs and reves perfectly fine. I initially thought the tps was bad, so i tried 2 others and got the same results. also made sure the iac wasnt stuck open. From what i can tell there are no other wires shorting out on the tps wiring.
