Questions from a newb...
Hi guys, I have a late 99 f-250 that is bone stock besides a DIY 6637 intake, when i first bought it i went through the entire thing, oil change, fuel filter change, etc. etc...anyway, some things about my truck bug me, sometimes when the truck first starts up and has not fully warmed up it seems to have a ton of power, the engine pulls great, but after the truck warms up a bit it seems to lose that pull and i have to step on it way more to get it going... then at other times the truck is always sluggish like this no matter the temp. When it feels sluggish its like the truck isnt responding to me stepping on the pedal. Could this be a sensor? If so, which one, ICP or MAP?? ( i've seen you guys talking about the icp but cant seem to figure out where it is...)where is it and is there a way to test it? Also I want to put a straight pipe on my truck, I live in Wisconsin and the temps get pretty cold, will this be a issue with the truck or will the stock PCM adjust to the new flow so I dont mess up my engine??
Thanks in advance guys!
