testing for stuck injectors.

[Lukewarm256]

i have 2 cars with what i think may be simular problems... stuck injectors. One, a chevy, probably has them stuck open, and the other, a ford, might have one stuck closed.

SO, the general question is--what's a good, easy way to find out which injector is stuck on a mpfi v6? anyone got some cheap suggestions?

thanks in advance.

You can take a long screw driver put on the side of the injector and listen.

Use an ohm meter and ohm each one.

I would check for power to the injector first.

Remove the connector from the injector while the engine is running, if there's no change in rpm you've located a/the misfiring cylinder, to verify that the selected injector is bad you have to rule out the valvetrain and ignition, if you have a injector pulser you can manually check each injector for correct operation
