    ok first off, the car is a 94 Galant. it has the 2.4 DOHC motor. my problem started when one day my rpm's dropped dramactiacally while i was driving. if i was going 70mph at 3k rpm, the idle would go down to like 1300rpm and i would get a check engine light. so if i keep driving, it'll go away and the car will run normal again anywhere from 2 minutes to as long as an hour. i checked to see if i was getting spark and cylinders 2 and 3 weren't getting spark from the coil pack. so i changed that coil pack out and now the problem only occurs half the time as much as it did. so my guess is i only fixed half the problem. i have yet to look at my plugs and the wires are in great condition but they are ok. would a fouled plug cause this? any help or any ideas would be great. if there's any info that you need to help me, just ask, thanks.

    hmm...not sure.

    I would do all the routine maintenance that needs to be done and that was possibly ignored.



    on a side note......I feel the problem is the diamond star itself, very unreliable

    if its ne thing like gm coilpacks it might have taken the wires w/ it when it went bad,

    check the plugs too

    thanks for the replies, yeah i know DSM scks but i only use the car to commute 120 miles a day to work. it's been pretty reliable thus far. i'll check the wires and the plugs as soon as i get off work at 4:30 in the morning. anyone else have a thought?

    i agree. the galant is considered a DSM.

    ocasionally, the 1.8L mirages have this problem. most change the plug wires AND the coil packs at the same time.

    you may want to sign up on a galant board.

    yeah when i checked for spark only one coil pack was out. i would of changed both but each one is like $80! i got the plugs already, i have yet to change the wires. also, i noticed that if i use cheap gas (arco) the problems occurs like 5 times more often. If i use chevron, the car will drive for a longer period of time. now, this has only happened once so maybe it's just a coincidence but do you guys think some fuel plays a role as well? or does the problem sound more like a spark issue?

    Good Fuel + Good Spark = Good combustion
    Good Fuel + Bad Spark = Not so good combustion
    Bad Fuel + Bad Spark = Little to no combustion
    Any Fuel + No Spark = Absolutley no combustion

    ^Just my theory.
