Had a CEL for the TPS and ISCV.
Ignition on, took the TPS plug off and set the multimeter to Ohms. Used the middle pin and the outer one on the left, nearest the throttle body. On mine the TPS is on the right hand side of the throttle body, as you look in towards the engine bay.
+0.5 closed throttle
+4.56 open throttle
I suspect the carpet was in the way a bit on open throttle, so might do it again later.
Sprayed some cleaner into the ISCV, and seems to be a bit better. I was getting 1500 idle speed, which is now normal, but it still drops to 500 ish every now and then.
Help appreciated.

Thanks John,
Ill try an ECU reset and see what happens... What happens if you use the other outer pin? I couldn't get the multimeter on it.
