Well, I got 3 of 4 to fire, an improvement but.... So rather that swap around decade old stuff, I did the Ignitech TCI and coil over plug swap. The install was plug and play, s till collecting parts for the MAP sensor to hook up to the Ignitech. Hopefully when it is all done I will get performace back to stock. But in the mean time it is nice to have a V4 vs V3.
