the other day my truck went crazy. crazy idle lightning bolt dash light flashing,and lost all power. i have had a p0441 code nowhave 2106 2118 and 2110 any guesses on what it could be? HELP!

 

Well the 0441 is evaporator system, but the others I believe are throttle control.

Check the entire evaporator system, especially around the cannister for leaks. Reset the throttle control and if that doesn't work change the position sensor...

 

is the canister right underneith the back seat on the 03 quad cab? and how do i reset the throttle control?

 

underneath, looks like this:


The 0441 is a "small" or minor leak, by chance, check the damn gas cap too. Cracked hose from the pump to the charcoal filter is very common. Should NOT be enough for a power loss, that's going to be the TPS system. Do a search, somebody gave a step by step reset in this section not long ago.
If you find you gotta replace the sensor, it's a relative cheap part and a 10 minute unplug/plug fix...
