I was driving my car monday on the way to work, car was driving fine. I stopped at a light then pulled off, I'm cruising behind this 18 wheeler in second gear waiting for the lane next to me to clear so I can go over, lane clears so I move over and kinda speed up in second gear. shortly after i got on it in 2nd the car starts to sputter around, so I'm like WTF! I pull over, with the car still running pop the hood and start looking around, didn't notice anything, close the hood and see black smoke rising from the back of the car. because I was still close to home I took the car back home, once I got home I shut the car off and tried to restart in and it started but was still smoking and jooking around. got dropped to work, when I got home I looked under the hood once more and tried to start the car but it didn't start, what the hell could this be, anyone ever go through this with their H yet?

pulled the plugs and they looked like this

what all is done to your car

 

head work- springs/retainers, cams, port/polish, and cam gears! Car ran good for about a week, then started this. my mechanic said theres a fuel problem, he has the car now and says he gonna dig into it and call me when he figures it out!
