Well after a friend of mine hopped on to the engine and looked back behind it he found the hose it had fallen off or was taken off at sometime in its life maybe while work was done to it but its been that way for at least 4 years or so. anyways after putting it back on it runs as smooth as a swiss watch.. no more bucking at hills smooth idle just great. but i need some advice as its getting cold and it sits over night it does not want to start takes like 4 times and putting the gas into it abit to get it started . after its started its fine . if you go somewhere then get in to restart it .it starts right up also. Not sure whats up there. battery is fine i was wondering if its my idle control valve that i bought used that i did not need that might be doing it. thanks guys for all the help...
