Throttle position switch
I was checking the adjustments of the switches on my 87 3.2 and found I got continuity at half throttle on the throttle position switch (WOT). I loosened the adjustment screws and moved the switch. It made no difference. I then adjusted the switch full travel in both directions and still got continuity at half throttle. If I close the throttle to less than half I lose continuity. The switch seems to be fairly simple. Has anyone seen this before?

Measure the resistance...it’s a potentiometer.

It's just a switch - with continuity around 75%.

Throttle position switch
I was going by the Bentley manual. It says the switch makes when the throttle is wide open. The manual said when the switch makes, it sends a signal to the DME to increase fuel enrichment. My concern is at part throttle it is increasing fuel flow to early.

Really? Just a switch? No wonder DME is so bad.....
