Just bought a civic ex 1998 red coupe. On the way home (300mi) the check engine popped up half way home. the brakes weren't working as they should. The brakes went soft and when I tried to slow down the wheel started shaking. I had this problem all the way home and can't think of anything to fix this along with a burnt smell when touch the brakes! Also had the fuel gauge move up and down as I was driving along with the rpms fluttering. Camshaft sensor maybe? Any help on these problems are greatly appreciated. Thanks guys!!!
