INJECTOR TESTING
How can I check my injectors without removing.
I checked resistance and driver side all 4 are 14.7 and passenger side all 4 are 16.2. Strange?
I hear about injector balance test (in service manual) but I have not that tester with at precise amout time open injector. I think that time is 400ms. If yes I can made that tester with my friend help.

Re: INJECTOR TESTING (jtjerry)
The injector on time depends on rpm and duty cycle.
At idle, 600rpm, the frequency is about 5Hz or a period of 200mS. There my On time is about 2-3mS.
E-mail me after Mar. 19 and I can hook up my scan tool to verify that On time.
I think you need to pull the injectors and use a graduated container to run a balance test though. In which case you run them full open for a fixed time and measure the amount of fuel that has accumulated.
