Jbandauskas Posted June 20, 2016 #1 Posted June 20, 2016 1984 venture has intermittent spark on #4 cylinder. The coil tested fine (within factory specs ). Since I have everything apart do you think it would be wise to change out the tci module?
cimmer Posted June 21, 2016 #2 Posted June 21, 2016 I would check the plug wires and caps first. How are are they and how do they ohm out? Rick F.
BlueSky Posted June 21, 2016 #3 Posted June 21, 2016 Unscrew the plug wire caps, cut off about an inch of wire and screw the caps back on.
bongobobny Posted June 21, 2016 #4 Posted June 21, 2016 Yah! That!! Or, maybe consider new wires as well unless they are fairly new (less than 10 years old) and new plugs. Did you see any green stuff in the coil secondary cap?? Yes, there is a possibility the TCI has a diode for that cylinder about ready to go south. How deep are your pockets?? There are no new TCI's to be had, but you can get an aftermarket Ignitech module. Replacing all 8 diodes in the TCI is a lot cheaper...
garyS-NJ Posted June 21, 2016 #5 Posted June 21, 2016 I don't think a bad diode (the ones that disintegrate), will cause you to loose spark.. Sent from my VS987 using Tapatalk
