Had my sparkplugs changed and none broke and the strong gas smell coming through the vents seems to be gone. The funny things is after seeing the plugs I didnt see anything that would say yep that's a problem.

now see, mine was the other way around, i changed my plugs at 50k miles as a prevenitive, which made a huge difference in throttle responce, but now when i first get in the truck and turn the vents on i can smell that gas like smell, or if im goin down the road and i turn the AC off for a few minutes... when i turn it back on it comes back for a moment then clears, it runs much better, not like i dropped a cylinder or something, its been almost 10,000 miles and hasnt stop

I had mine changed at 100K and I have noticed the gas smell also when I first crank my truck up. Any idea why this happens?

only thing i can think of is that when you unplugged the injectors to gain access to the coils, the injector orings may have sealed well/or poorly, depending on the issue each of you is having causing a very tiny leak and then a smell. a small fuel leak my never be noticed because the liquid would evaporate leaving the smell for the vents to pick up.

just a wild guess tho

Plug backed out. See my thread about fuel smell.

It's very important that the plugs be torqued properly or you will get this smell.

Did the same with mine after plug change, I retorqued them to 25lbs and the smell is gone.
