[QUOTE="jeepjoe43, post: 429378, member: 19255"] I agree with Feral, but would add inspect the wires to the connectors, too. Back in the 80s & 90s Chrysler was sacrificing quality for weight due to CAFE regs. My gremlin was a stressed/broken wire on the plug to the coil, cheap wire. As I understand it, a CPS failure usually manifests when it gets hot, but don't rule it out. [/QUOTE]
