As most of you with older cherokees have already experienced (or probably will soon), the reverse lights tend to stop working, or work infrequently, when put into the mentioned gear. With such a common problem, it was very easy to find a fix for this.....cleaning the NSS switch. After doing so (and also having ruined a completely good pair of shorts in the process) I decided I might as well go all the way, and grease my chassis, as well as clean out my throttle body. After finishing these tasks, I decided to take the jeep for a spin to see if I could notice any improvements in performance.
This is where I ran into a new problem. When I started the engine, it was running about 700 RPM faster at idle than normal. I assumed this was probably due to the throttle body cleaner I used, so ignored it thinking it would go away.......160 miles later it's still doing the same thing. I tried cleaning the IAC motor, which was quite dirty, and this didn't do jack. So I am now trying to figure out if either the IAC motor or TPS are shot. I'm pretty sure I know how to test the TPS for proper voltage readings, but I'm not exactly sure how to test the IAC motor. Any thoughts?
Thanks
