I believe it is NLA. Mine crumbled and I am experimenting with a microswitch I picked up at Grainger. It was cheap. The screws don't line up, so it is only mounted by one screw. So far so good.

I found that I had much better throttle response after I disconnected the idle switch. BTW, my idle switch worked fine.

With the idle switch, the rpm would momentarily go below the idle setting when revving the engine and then letting off the throttle.

Without the idle switch, the rpm does not go below idle and recovers much quicker.

Why dont you stick with one post about your running problems, instead of so many posts about the same thing?

So now you think its the switch. Im my opinion they only work of they dont. You have a low mile car, so I doubt its worn out.

Whats the condition of your harness BTW?

I recommend getting a Wideband O2 sensor ( Or loan one) and then you can see what your AFR really its.
