Visible Fuel Injector Spray Pattern

["content22207" <brobertson@xxxx>]

Re: "poop poop" noises -- a spark plug that has come loose, or lost
its threads (actually, threads in the head), makes just such a sound.

Re: visible fuel injector spray pattern, see Message #32067. Is a
Volvo procedure to set fuel mixture, but could also use just to see
pattern. Don't forget to plug injector port. Guarantee engine won't
run otherwise.

Injectors can only be cleaned with special equipment. Have a little
spring and other goodies inside:

If fuel filter is intact, can't imagine anything big getting in there.
Might get gluey from old fuel deposits, but a tank or two with
powerful cleaner should break that down. You'd be surprised what a
long highway burn can accomplish. All my cars, Lincolns included, are
never as happy as after a trip up I-95.
