the only thing that I can think of is you must have put the crank pulley on to for and its wedging against the timing gear and its pushing on the bottom of the block front journal
do not run until you check it out

well first of all I don't think the pulleys have anything to do with the problem, they wouldn't put the check engine light on unless you have a newer model with a knock sensor. then the squealing is causing the knock sensor to retard the timing giving you the lack of power... I would try and find out where the squealing is coming from... If the pulleys you got were for that make and model you can't put the crank pulley on too far.. the first thing I would do is have the codes pulled from the computer that will give you a place to start... If it is a code for the knock sensor then I would see if you have a tensioner or w.p. or alt or a/c something like that locking up where the bearing is going bad... if the code is for something else follow up on that.. changing the pulleys would not make the check engine light go on unless there is a serious bearing problem somewhere causing the knock sensor to come into play... so pull the codes first and go from there
