I've been having a stutter from the engine while idling in gear and have replaced plugs & coils to no avail. I did some research and have come to the conclusion that my timing belt could have slipped. I would think this to be unlikely but I am approaching 250k miles and to my knowledge the timing belt has never been replaced. I've bought the Gates TCKWP298 timing belt kit and will be working on it this weekend. I'll only have 2 days home from college to get the entire job done. Does anyone have any pointers? And is it possible to change the timing belt without removing the A/C compressor? I'm also not certain about lining the belt up. I know the mark on each pulley should line up with the I mark, but I've seen some people line up the marks on the belt with whichever letter is to the side of the I, while others line them up with the same I mark as the pulley. Anyone have any insight on this? Thanks in advance.
