I need some help. Recently my 2006 4.7L has a bad smell of gas in the cab. The Jeep doesn't drive any different or run any different at idle. I changed the spark plugs over the summer but only started to smell it recently. There are no codes either.
Also, I don't know if it's related, but the engine started squealing intermittently on a cold start up at about the same time. It continues to do this until it is at normal operating temperature. It isn't a consistent squeal like a bad belt. I have also tried belt dressing and it didn't help at all.
I have searched on both of these and haven't been able to find much. Any help before I take it to the dealership would be great.
