Hey guys, yeah so today my check engine light came on and it was a code about the idle control sensor or something like that. So i go up to the ford dealership to see what it actually was but they couldnt get me in today. so im leaving and the light goes off after being on since about noon today... ill still get that checked out.. butttt heres my main problem, I just did the oil change about 3 or 4 weeks ago. Motorcraft oil filter and valvoline synthetic oil, i put 5 or 6 quarts in. well after driving it about 700 miles i would say, i checked the oil today and the thing was almost empty!! this is the second time this has happend, the car does not smoke even when i rev it up to about 6k rpm.. there are nooo oil marks on the ground and no signs of leaks ne where. I have noooooooo clue what the deal is. Im going to get that checked out at the ford dealership on saturday, does anyone know what could be the problem here?? and last thing, i was just experimenting with my car and i got on it pretty hard, 1st gear and shifted to 2nd at about 6500 rpm (stock computer, engine).. is there a rev limiter on my car and when does it kick in? because at 6500, my car just stopped going.. it was like i went from 1st to 5th gear.. i dont know much about the technical side of cars yet, im learning as i go.. and im very anal about my car and want to make sure everything is ok.. also, do your guys' cars seem slower after driving them for about 2 months? because when i first got it, man was it fast but now it just feels slow.... like realll slow.
