I pulled off my TPS and checked the resistance (fully depressed to full extension):

Narrow Range: 0.22-4.75 Ohms
Full Range: 0.11-4.86 Ohms

Reason I ask is when I adjust it on the vehicle I get the one LED lit and Narrow Range at 1.02 Ohms. The Full Range is 1.19 ohms, not the .60-.90 ohms like it should be. Idle is never consistent and frequently pulsates. I unplugged it and pulsations stop.

I forgot to add that when I measured resistance there were clean sweeps for both Narrow and Full range.

 

throttle closed your multi meter should read 1 ohms... wide open throttle should read 4-6 ohms, I believe. it should sweet smoothly between closed and wide open throttle with no "flat" spots. I don't know what you measured above so... hope this helps.

These were measured off the car and plungers fully depressed to open:

Narrow Range: 0.22-4.75 Ohms
Full Range: 0.11-4.86 Ohms

On car after warming up and car off resistance was:

Narrow range 1.02-4.75 (note the plunger is not fully depressed when at 1.02)
Full Range 1.19-4.84

My concern is the 1.19Ohms on Full Range plunger which is not adjustable and is greater than the 0.6-0.90 range.

Hope that makes sense?
