ok, now for a long time my 89 tracker has had a bad loping idle. I finally got around to taking it in to get it fixed, and as expected they told me the problem was with the TPS.
Now, i'm wondering what exactly the throttle position sensor does, as they mechanic's way of fixing it, was simply to unhook it. I would have assumed it was put on there for a reason, but everything runs smooth now with it gone.
Can someone please tell me the reason for this? i'm wondering if it's something i should replace, or just be happy that things are running now?
