Unable to set timing, 3vze v6 89pu. Timing jumper not working?
I am trying to get my 89 pickup smogged and when you jumper the diag plug the idle does not drop. Currently you see the timing mark jump around.
v6 3vze
i have adjusted the throttle body and tested the tps. Everything is working.
I dont know where to go from here now. It idles perfect, just doesn't drop rpm with the jumper.

Start by checking your TPS, is more likely to be the culprit here, as soon as you jump the diag plug the RPM's should drop right away. http://www.4crawler.com/4x4/CheapTricks/TPS/index.shtml
