Ok i got a situation
my MAF sensor im pretty sure is bad so i took it to one of my friends whos like a certified mechanic or whatever, he said yeah hes 99% sure thats what it is. so i went and got another one off ebay & put it in.

it is still doing the same thing: its like it skips, doesnt idle well goes up and down, sometimes even dies, and when im driving it kinda seems like its miss firing (i describe it as kinda a "hiccup", and the check engine light comes on.

now this morning before i left for work i decided hey lets un hook it see how it goes...now theres no check engine light, it drives perfect, no hiccuping and it idles just fine

idk whats going on with it just seemed kinda weird to me
