    Hi,
    I have had a 92 excel for several years now, and it has been totally
    trouble free untill today.

    I noticed it running very rough, and have determined that it has
    suddenly stopped fireing on the leftmost two cyclinders.

    I checked the plugs, and found them to be clean and dry with no fouling
    evident... Just to be safe, i replaced all 4 spark plugs, roter, cap
    and ignition leads.

    A compression test reveals that compression is normal in all 4
    cylinders

    What are the types of things that can cause this, and what else can i
    check without pulling the motor apart ?

    Could it be a problem with the EFI ?

    regards,
    Michael

    Could be an EFI issue. Did you verify no spark, or do you just know you
    have a miss?

    Possible the wires could be switched? Firing order is 1-3-4-2.

    Possible clogged injectors.
