Over the past few weeks I have been trying to diagnose a difficult issue with my 2002 toyota 4runner which involved the throttlebody. Initially I came home one day and my starter wasnt working, I replaced it and then in attempting to start the truck the throttle body was damaged(later I discovered there was a clutch that had failed due to the agressive attempt and trying to open the throttle). I ordered a rebuilt throttlebody from ebay for $500(the dealer wanted $950 for a new one) and put it on, which solved the issue.
However a few weeks later the engine started stalling randomly while idling. I popped the hood and the took the throttlebody off and examined it for any issues. when I reinstalled it the engine started up and revved all the way to 3500 rpm and idled there. at this point I tried looking online and even through the toyota field service manual for my truck with no luck on how to diagnose the issue I was having. A friend of my mom's had turned her on to Sasa, and all of the work done was excellent quality. As you can probably tell normally I do all the repairs and maintenance on my truck myself. I decided to take the truck in and have him take a look at it, and I also gave him a few spare parts that I had gathered in order to help him troubleshoot. a few hours later, after he had finished another job, he got back to me after having done some troubleshooting on my truck. He found that the issue was a bad acelerator pedal position sensor in the rebuilt throttlebody, something that I had overlooked because I had assumed it was a wiring problem. Overall a great experience and very satisfying to find the solution thats been plaguing my truck for weeks now.
