    how to find an OPEN fuel injector ?

    I had one of the original injectors stuck open on my HO.

    Only found it when another one failed closed and caused a miss. Just looked at all the others while I was at it and saw the pintel stuck open on the other injector.

    I put a set of new bosch injectors in there about a year and 4 months ago. They are the 4 spray type. The car ran great. Now I having erroneous fuel readings on the trip minder and worse fuel economy.

    The engine runs fine.

    How could I isolate a stuck open injector?

    pull the plugs. I would expect the stuck open one to be noticeably darker than the others on that side. Actually I'd expect 3 to be too lean and one too rich.
