Please help. My tach started acting up. Then later the engine cut out then a really loud back fire when it started going again. After that the next day it was hard to start at first but when it started ran fin for 12 min until I got to the property of work then started bucking. drove it to my parking spot and that is where it sits.
Could this just be the coil. I have power at the main power wire but no spark at the plug (checked with the screwdriver method). Coil came out of my old Camaro so it is about 6 or 7 years old.
