Hi ya' ll I pulled out the # 2 idler pulley and the Timing belt was lose because I could spin the roller with no trouble , but when I went to put it back in after changing the Knock sensor the belt poped out of the gear a little and when I put it back down it was a little tight , I had to put a little force on the Pulley to get the bolts to start not much just had to push down a little , but now the Pulley is tight not like it was when I took it out, did I mess anything up or is that ok ?
