NEDD Advice, Rough running , missing, backfiring?
Ok fellow Jeep Heads, I have an 94 ZJ 4 door, 4.0L automatic, 2WD. The last 2 nights on my drive home from work, when I get stuck in traffic my ZJ starts to idle rough, act like it is starving or wants to stall, backfires(?- making a popping sound), and when I check the codes via the keyswitch method I get code 12, 41, and then 55 (the end code). Any ideas? Any help will be greatly appreciated.
