1) Check engine light flashes 5 times. Is this a big deal? Just buy a new Exhaust temp sensor? 2) It has developed a squeal that sounds to be coming from the clutch area at an idle. Give it a little throttle and it goes right away. Did not do this before I had my clutch removed to install SLP torque arm. I do not like the sound of it at all and would appreciate any info on how to fix it. 3) Intermittent speedometer. Sometimes it works but mostly it reads 0. Really not sure if it is even reading right when it is working. Help would be greatly appreciated. Thanks
