s13 Help with idle and temp gauge

[Dman2195]

I just bought my car ka24de everything stock except cai and the car was idleing really high so i unplugged to tps and adjusted the idle some, now it doesnt stay consistant it jumps up and down 500+ rpms each time the down 500, and the temp gauge doesnt work, bought new ecu sensor and gauge sensor for coolant installed them both and the gauge wont move off the needle stopper, idk how to know if its running rich or not? help, thanks!

If your idle is "hunting " check tps voltage and make sure its between. 3 and. 5. Also check for vacuum leaks. To test your gauge take the single wire temp sensor wire and ground it to chassis. If the gauge itself pegs to hot than the gauge and wiring is good.

what would cause come sr's to run at .3 and others to run at .5.

.3 volts= leaner idle, correct?

1.) Position of the TPS. It can be adjusted, and should probably be at 0.5V.
2.) Nope.
