That is the idle up control, when you turn on the lights etc.
and I think it makes the rapid da da da da da noise when it's
active, heard it on my 89' from the very beginning. you don't
need it to run the Trucklet, so if you cant get one, don't let it
ruin your trip

WOW ! You you hit the nail right on the head.Since I first got the Tracker it has "ran" fine,but when you turn the lights on it would make that da da da da noise.FREAKED ME OUT! Once I was able to track down which piece was making this noice,I simply snipped the wires and the noice stopped and the engine stayed running.Seemed to run fine.In fact I have two outings on it since.
I became alarmed when I noticed the goo around the plug on my map sensor had melted and was running out like chocolate syrup.I began to think cutting the icv wires was causing this problem with the map sensor.
If I can run without the icv,that would be great , but then I still have the issue of an idle goes up and down when I first start the engine,and then seems to remain high.
Thanks
