89 3vze, cannot check timing, timimg mark bounces around
I am trying to get my 89 smogged and when i try and check the timing its bouncing around so i cant get a reading.
When i short out the diagnostics jumper, the engine speed does not change at all. the check engine light blinks constant, so it is in timing diag mode.
No check engine light.
Idles fine @800rpm
What should i check? what would cause this? new plugs, cap rotor, wires.
Thanks!
