My last thread got off the track due to multiple issues ( replaced fan motor, replaced in tank pump twice due to faulty new pump.)
This morning I was going to test the timing and noticed it is jumping around,from
gets steadier as rpms increase. I tested the timing on my 93 model and it is rock solid. What would cause erratic timing at idle?
I tested ECT per the Bernstein; 1.4v at startup 100*ambient, .517 when engine warmed up appx 180*?? ( Don't know how to properly measure temp at operating temp.)
