2G high jumpy idle and cel P1105

[mheidemanjr]

before you b#%ch at me i searched first but no one had the exact same situation so a new thread is born!

when i first start the car the idle is at 1k rpms after i get it going down the road and push in the clutch it will stay at 2 k for a min then drop to like 1500 and the to 1200 and stay there, that's to high right? any ideas what could be causing this?

i did a boost leak check today and its all good no leaks held 15psi for about 2min before dropping to 1 or 2 and i could not hear nothing also the cel is on throwing code p1105 for the fuel pressure solenoid. i tested it by hooking power and ground to the solenoid and it open and closes so is it still good or do i have to do a resistance test?

any input would be great thanx!

check the voltages on your tps and isc.

check the voltages on your tps and isc.

what should the voltage be and where are they?

i forgot the isc voltages off hand by tps should be .63 volts i believe.

You take off the connector on the tps and isc respectively and using a volt meter check a certain combination of the pins. Search for it and you will find you answer.
