#4 of 6 Nice van with a big problem by emaydogg Sep 14, 2008 (6:37 am)
I just purchaced a 1986 Chevy Astro van and I know that with a van of that age there will be problems. I changed out the fuel filter and then I added new wires and spark plugs. I am still having the problem when I get to a red light the van wants to cut off. What could be the problem? Replies to this message: jonkez (Oct 12, 2008 5:17 pm)

The Fix for the random misfires is simple: just use a clean towel and spray some WD40 liberally to the towel, carefully rub the solution on the PLASTIC PARTS ONLY (Interior of Cap)! None on the Pins or the Carbon center! This has proven to be a long solution to this problem! I have had no misfires for TWO MONTHS since I did this! The BULL about using a GM part is just that BULL! Enjoy!

Replaced it and all the problems went away.   I am not kidding that was the problem. if your turn signal is acting up I would look at this as the problem.   My van has run without any problems now for a year now. Who would have thought that this would cause the problem.
