So I was coming home from FT Lauderdale back to Winter Haven, and on SR-60 my Jeep started to do the shake and then CEL came on full flash, used my scan tool, Cyl 4 Misfire, hotswapped the plug at an auto zone and boom all good until it started happening again, took it to my mechanic he said the plug broke off in the block, he extracted it, threw another plug in, and now two days later CEL came back on after it was idling rough at a stop light, fyi this is the 3rd motor that I got from LKQ so I’m trying to not make the 4th time a charm! Please help!
