hard/weird starting
 

ok... last night i went out to start my truck and when i did it took like 6 seconds of cranking on it to finally start... once it started it sounded like it was barely even getting enough fuel to keep running. so i turned it off right away and tried it again and it started just fine, i kept doing that a couple times and on like the 5th time i did it again it did the same thing, crank for about 6 seconds and barley had enought fuel to keep running but i left it alone and it was running fine... even some times when im about to stop and i put it in neutral and let off the gas and my rpms go up a couple unrded and drop a couple hundred to normal and back up a couple hundred and the backs down to normal. any way does this ever happend to anyone else???? thanks for the help!!!!

Check the wire from your AC system pressure sensor where it goes behind the engine. It is likely frayed. I also sent you a PM regarding the other probable cause.
