0101 is usually a vacuum leak of some sort or the MAF. Could be that the MAF is sitting too low or too high or is it possible that you put it back on during installation backwards? Did you clear the codes to see how long before it came back?

i looked online to see how to reset the check engine light but the online thing that mainly showed online was reseting the maintenance light. i also tried taking out the fuse but its still showing....i screwed on the maf in all the way but i havent tried rotating it...i'll turn it around tomorrow and well see if the lights still there. but how could the maf be either too high or too low?
