    #1 Do a proper compression check on all 3 cyls. If even across the 3 then move on, if not find out why. NO MORE than a 12lbs difference.
    #2 If compression is ok, check the catalytic converter for restriction or breakage. If ok move on.
    #3 check the fuel flapper in the pickup. Here is a link on how.
    #4 If all of the above check out ok, you have additional problems. Continue with this thread advising us of the results of #'s 1,2,3 above.
