Howdy folks,
I got a issue that I cant seem to find the cause of, first off my check engine light comes on intermittently (no 1 cyl position), and the abs as well. They come on and off all the time. Its been to 3 different dealerships, checked all the sensors, timing, abs hcu, the abs module, the sensor rings ect. It all checks out, they said to check harness connections for corrosion or heavy water issues. I checked as much as i could, cleaned all the contacts with electrical contact cleaner, made sure they were nice and snug again. Still intermittently flickers. 2 weeks ago I drove the alcan, Spokane to Anchorage and it was rather annoying. Any suggestions as to what I should try next. The distributor, cap, rotor was just replaced. Any info would be helpful.
