Failed!?........hmmmmm, my Dak passed the test in June 2000 without any
problems, with 125,000 miles on it. I would spend the $2 and get a new PCV
valve, and spend another $7 for a new set of Autolite Coppers, I am using
3924s. As far as plug wires, if you can, spend the extra money and get some
good plug wires. I spent $60 on the MSD 8.5MM Super Conductors wires about 2
years ago and think they are some damn good wires. They are MSD PN#32189,
which are for 94-97 V8 Rams. I would also run a bottle of fuel system
cleaner through an entire tank, and run that tank down before
testing.......go in using a fresh tank. Just my thoughts.
