I have had my truck for four years and during that time the engine light, the one showing the motor has gone off 4 times. Once the dealer told me I had not sealed the gas cap correctly, the second time they replaced the gas cap. Last week it went off again, I re-sealed the gas cap and it went off...then tonight again it went off. Any suggestions or should I just keep re-attaching the cap

Welcome to the forum!!! Are you turning it 3 clicks every time you tighten the cap? is its just not tightening or what?

If the code that is setting, is a small leak in the evap system, then the cause COULD be the gas cap. But the gas cap is just one of many things that could be wrong with, ranging from rusty filler tubes, loose clamp, bad o-ring on the sending unit, cracked hose, bad canister purge valve......pretty much anything to do with the evap system. There are special tools and smoke machines that can be used to pin point the probllem very easily.

Are you saying that since last week the check engine light has not turned off? If thats the case, it could be the gas cap, when mine did that I called my brother (a tech) and he said it takes a certain number of cycles of turning the engine on and off (I wanna say 30-60) before the light will go out. If it went out between last week and now, and is coming back, then I have no idea.
