INTERESTING!
I just checked the TPS. The probes from my DVM don't fit directly into the wire harness so I just stuck a little jumper wire into the harness.
The resistance between the Orange and Pink wire, Which I think is the sensor output starts at 0.98 when in neutral. As the throttle is pressed forward it goes up to about 1.2 at around half throttle end ends at 4.7 at wide-open throttle.
Between the Orange and Red wire, which I assume is the input to the sensor the resistance is a steady 5.02 from neutral to fully open throttle.
SO....
Manual calls for 0.50 with throttle valves fully closed.
When I reinstalled my injectors I noticed that when in neutral my valves appeared to be fully closed. Should I still make go through the steps of disconnecting parts to confirm my throttle valves ARE completely closed? Im not trying to be lazy and save a step, rather I just hate to go adjusting and moving stuff that WAS working (or seemed to be) before.
Also, I am measuring resistance. does the fact that I am measuring this using my little jumper wires affect the resistance?
These numbers, especially the 0.98 in neutral, seem to be out of spec. I think spec should be 0.5 to 5.0. Could this be my issue...slow idle, running rich, increased fuel consump, and loss of top-end RPMS.....
Should I attempt to adjust the current TPS or just replace w new one?
