I just bought a 2006 F150 with 39,000 miles 7days ago. The day after I bought it I noticed a strong raw gas smell in the cab and outside of the vehicle. I took it into the shop, and they were unable to find anything wrong. So I am here pleading for help!! Today I took it out and it is running very rough, not stalling but close. I let it warm up and accelerated and it chugged and powered down. It flashed a check engine light, but it didn't stay on. Just wondering if anyone has any suggestions, I would appreciate it!

sounds like you have bad injector, almost positive. if you keep running it, or you may already have wrecked that cylinder.....might get real $$$
