Question
I have an ongoing problem with my car which has me baffled first I changed its break pads and cut the disks yet,it continues making that squeking noise when I break what could it be?

Second, when I accelerate sometimes it stalls alot then it stops for a while and then weeks even months later it begins again. Any help would be helpful Thanks J

hi  did you do the front and rear brakes, I would look for the sensors that rub when the pads get low you might have to bend them back a bit, or look for any shiney spots thats where its rubbing, and do you switch gas you might be getting a bad load of gas once and a whileadd some dry gas to the tank
