stick to one post??? OKAY........ you state the 'check engine light is not on'. Does it come on and go off for its 'self-test' or is it completely inoperative? Do you have a fuel pressure gauge? You state it is 'missing a lot' --Have you pulled the spark plugs and inspected them (make sure to keep track of what cylinder each came out of!!!)
