I have been playing with the timing on my 89 4Runner's 22RE recently and I can't seem to get it where it should be. I know the basic process, but what I can't figure out is what I'm supposed to "jumper" while setting the timing. There are some instructions under the hood that show a diagram, but I don't understand it. I know the timing is too far advanced because it pings just a bit at low rpm under load.
Do explain...
Also, is there a what to manually set the idle speed or does the computer automatically do that?
