Another thing to check is to make sure that the spark plugs are all properly gapped. Both are items that can cause the type of problem that you're describing on your car, which sounds like improper burning of fuel in the cylinders (either too much, or improperly atomized). If that still fails, you *might* need a CO adjustment like my car did after 20 years, but that's more of a final repair, and takes an exhaust anylizer to complete. -Robert vin 6585 "X" To address comments privately to the moderating team, please address: moderators@xxxx For more info on the list, tech articles, cars for sale see www.dmcnews.com To search the archives or view files, log in at http://groups.yahoo.com/group/dmcnews Your use of Yahoo!
