Hey guys, i have a 95' 676. I just bought it and its hosed up, when i start it it idles at at least 2000rpm and never gets lower, then if i shut it off its really hard to start, i have to almost flood it to start it.. i know nothing about mazdas, so treat me like an idiot, im going with timming or vac leak,

 

Is it a V6 or 4 cylinder? Give a check to the throttle cable and make sure it is not holding the throttle open first off. Also pull the intake hose off the throttle body and make sure a rag or something was not sucked into the intake and caught up on the throttle valve. Have seen that a few times. I would expect a vacuum leak to be causing more of a rough idle rather that elevated to 2000 rpm but if is a 4 cyl check the intake maniold gasket as they have been known to blow out at the bottom corners especially.
