    Engine Problems!

    Hey, iv got a 1994 yj 2.5L and it isnt running right. it seems to run ok on idle but as soon as i push the gas it bogs down and seems like its misfiring and if i bring up the rpm it misfires and runs rough, its got a aftermarket cold air intake on it that was put on by someone who owned it before me. and there is a hose that fell off of it and i dont know where it came from but the hose is still on the pcv valve. could this be to much air being sucked in? and i replaced the spark plug wires. any suggestions would be appreciated. thanks
    Keep the wheels turnin

    plugs, distributor cap n' rotor. air filter plugged?, fuel filter plugged (thinkin air filter or plugs as the most obvious suspects though...) could have something to do with that hose IF it's supposed to be hooked to the PCV system/ vaccuum leak....

    Lot's of little inexpensive things it could be... try air filter first, take it off and start it, see if that makes a difference (make sure you don't suck in any dirt when you take it off...)- then check your plugs maybe dirty inproper gapping or maybe just old and need new! Start cheap, work your way up!

    I would sugest checking fuel pressure and vaccum leaks.. That hose which feel off and you are unable
    to find a location... find the location... it should be somewhere on the manifold or throttle body as those are
    the only places that vaccum hoses are attached...

    i took off the air filter assembly and cleaned every thing and started it without it on and it ran fine. then cleaned the air filter and put everything back and it seems to run ok now, thanks
