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.

Re: Fuel Injector Flow Test
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.

Re: Fuel Injector Flow Test
Thanks Frank. Have you ever heard of one testing at 17 ohms?

Re: Fuel Injector Flow Test
probably need to look for consistency in ohms from inj to inj...unless you believe they are all bad.

Re: Fuel Injector Flow Test
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.

Re: Fuel Injector Flow Test
Just tested them and they're all at 15.4 or very close.
