for the throttle switch....is it the little micro switch on top of the throttle body? or the throttle position sensor.
Get the code (check engine light)on constant when i'm coasting down a hill in gear, blip the throttle and it goes out.

Any ideas?
2.3 NG is the motor. 88 is teh car.

I was getting this code when my ISV was sticking open. Fixed the ISV and that throttle sensor code went away.

FYI... switch on the top of the throttle is the WOT switch, and there is a switch on the bottom for idle (closed throttle).

cause a high/erratic idle? My idle speed is smooth and stable, I clean the little bastard on a reguular basis and eliminated the "oil injection".

So I should suspect a actual switch or circuit fault then?

Any way to source the switch from a place like Radio Shack?

TIA

engine rev'ing itself from 800rpm to 1500rpm in a constand cycle... because the ISV was stuck open, but the idle switch was engaged, it was modulating fuel pressure through the DFPR (little box on the fuel distributor with the 10ma signal) to control idle.

Touch the throttle, and it would rev up to 3000rpm... because of the air going through the wide-open ISV.

A switch could be sourced from an electronics supplier... but you'd have to search through parts catalogs to find ones that fit the same dimensions. I would love to pick up a new set from the stealership to see who makes their switches... then source those switches and return the harness to the stealership!

I haven't got a chance to dick with it yet..

I would assume these switches are NLA from the stealer? yes/no?

Top and bottom are not the same.
