so my girlfriend has a 2000 eclipse with a 2.4 4 cylinder, this past winter her father did a t-belt replacement on it and did a really good job but ever since then the car has been really sluggish, now she don't care but when i drive it i care a lot because for 1 its annoying and 2 is can be a safety hazard. now im guessing the timing is off, how do i check the timing? im not expecting a lot of you all to know this because this is a nissan forum but maybe if i advance it a bit it will be back to normal. also the tranny fluid is kinda dirty ( i know i need to change it soon but money is a concern right now) but i wouldn't imagine a dirty transmission wouldn't cause this. if you can help me thanks! if not don't sweat it i'll look on some mitsubishi forums, just thought i'd ask here first.
