now that my timing is set right my idle is at around 900-1k rpm. i wanna check my tps voltage, is it supposed to be at .98-.99 volts? and what wires do i check the voltage at?

 

It probably isn't the TPS. Start by warming the engine to norm. op. temp. Then shut off the engine & disconnect the battery for 5+ minutes (not much more,you want it to pretty much remain at norm.op.temp.). Then reconnect the battery, restart and observe idle. If that didn't do it, with someone w/ their foot on the accellerator, disconnect the IAC. The idle will falter & try to stall (If it dosen't, your IAC is bad). The person on the accelerator should catch the idle & maintain it at 675(+-)rpm. It will fight for 30-60 seconds but will settle in after that. Maintain for a minimum of 2 minutes. Then shut it off, reconnect the IAC & after 1 minute, restart. You should be looking at 675 rpm. If you have 675rpm, Turn on Lights, A/C, whatever you have that creates an engine load, and let idle for 2 minutes, then shut off for 1 minute. Re-rangeing the IAC is many times required after base timing is advances more than 2 degrees at a time. This assumes no Vac system leaks, a solid ignition system & no active error codes. When you start the engine warm, it should start around 1000(+-) rpm, then settle to normal idle w/ in a minute, max. If it doesn't, tap the accelerator. Lubing the throttle cable at both ends is a good idea.

 

i still what to check the voltage so see if it is in spec.

 

Jumper across the hot side. read between the other side. Between connection & sensor.
