Rough Engine in mazda 929
hi all,
My problem with my 1993 Mazda 929 is that the engine is very rough and loss of power. idleing and running and all the time. i changed my cap, wires, plugs and it is still the same. I read some other posts and they some say that they found one fuel injector bad, if that is the case how do i find out which injetor is bad?. is that my problem too? also some smoke also comes out of my exhaust. can it also be a leaking vacuum line? if so any ideas which one? any help would be greatly appreicated THANKS
