1989 sidekick misfire when cold or when under electrical load
#13
I read your post again #1
no new spark wires (mag is best)
new cap.
new rotor
new standard spark plugs? set to .028 " never out of box with gross wrong .045" and no bad to the bone surface fire spark plugs of any shape kind or form , $1.59 spark plugs as car had new.
VR gap set.
checked that both the vacuum advance works, with the a real spark timing light,? and a leak down test on it first? can be seen to work with vacuum connected then not.
then makes sure the advancing weights inside this old DISTRIB still works after 29 years of rusting ? the tests are in the manual. for 89s. it works just alike a 1096 USA V8 engine, this distrib.
discounting the VR and ignitor, the vacuum and centrifugal system is all pure mechanics.
im sure you did that but just want to be clear.
