So, my son's 1st vehicle is a 1994 ranger XLT 2wd. It's getting better, but subzero temps exposed an issue.. I've figured out that my coils are good, but cylinder 1 spark plug isn't firing ever, and cylinder 4 is random.. all on the exhaust side (rear coil) all others firing correctly. ICM? I do have 12v at both coils. Thanks for any help.
