Default Fuel Injector Flow Test

Does anyone know of a simple way to flow test fuel injectors? I'm chasing a misfire and would rather not drop $600 for a new set if I don't have to. I will do the OHM test as well.

There is a full set of 94 injectors in the for sale section at a good price. 94-95's are fine and not bothered by the ethanol that troubles the 90-92 cars. I wouldn't hesitate using them.
Best of luck.

Thanks Frank. Have you ever heard of one testing at 17 ohms?

probably need to look for consistency in ohms from inj to inj...unless you believe they are all bad.

You're welcome. See Lees post above and look at his site for injector testing also. Marc Haibeck's site has a detailed way of testing all the injectors with the plenum on.

Thanks Frank. I bought the injectors you put me on to, so hoping my problems will be solved. I also replaced the coils and am about to replace the fuel filter.
