Q: Permanent DTC Code cylinder 4 misfire on Jeep Wrangler
Check engine light came on for a cylinder 4 misfire. I had all plugs, coils and gaskets replaced. I now have a permanent DTC Code on my car. Maybe this happened because my check engine light was on for a while but now it will not clear out with a scanner. I had a drive test done on the car and it cleared the code for about 5 minutes. I am 99% sure my jeep is fixed. I just would like to know how to clear the code so my check engine light will stay off.
My car has 55000 miles.
My car has an automatic transmission.

I was driving my truck and it made this "poof" sound as if something blew. I lost everything--brakes, power steering, and it stalled
Hi, thanks for writing in. It is possible that the "poof" and exhaust smell (rotten gas smell?) both originated from the catalytic converter, and sulfur deposits in the converter.
