So I have been following the how to set advanced timing post found here How To: Adjust or Advance Timing
I have used this in the past without any issues. However when trying to set timing after my head gasket replacement I am having a strange issue I am hoping someone on this forum could help with. When checking the timing without placing the jumper on E1 and TE1 I am getting about 15 degrees. I follow the directions to jumper E1 and TE1 and this makes the check engine light flash. I am still seeing 15 degrees.. So essentially I am not seeing a smaller degree of timing with the jumper installed.. Right now I have just left it at 15 degrees and it seems to be running good.. I checked both knock sensors and they are plugged in.. No check engine lights. I did remove the Pair valve and the EGR. That should not make a difference.. The only other thing i can thing of is I replaced the ECM with a unit from a 94 due to my 93 ECM throwing 83, 84, 85 codes known issue with the early 93 ECM's . Anyone seen this kind of behavior?
