where are you getting these codes we DO NOT use any decimal points in codes and engine codes all start with "P" and are 4 digits

Customer: replied 1 year ago.
OK try the numbers without the decimal points that's what my van gave me was decimal point so try 1684 and 0304 instead engine idles with a skip when at a traffic light and have pulsating interior lights
Expert:  bill replied 1 year ago.

ok the one to concern with is the P0304 which is #4 cylinder misfire, # ***** is in the FRONT and the center cylinder, if the engine is skipping, start at the basics , a worn spark plug or faulty ignition wire can cause a misfire (skip) as well as internal engine problems, if the tune up parts are all OK and correct (spark plugs and ignition wires are changed at 100k ) then I would run a compression test and look for a LOW cylinder compared to the others, normal compression on this engine is 150 to 190 psi BUT ALL cylinders MST be within 10 psi of each other
