Is there anyway to test these off the car?

Or without it running with the plenum off I want to be sure thats it.

just wondering if anyone had a write up before I thumb through the FSM

John,

Run a hose from the air pump directly to the Differential MAP sensor bypassing the solenoid. Cap off the lines going into and out of the plenum area. See if you are then able to use secondaries. I'm assuming your secondary vacuum pump is working.

UPDATE

I folded and bought a tech 1.

Well I didn't even have a instruction manual but it seems to have everything else.

I checked the injectors and low and behold when I turn off # 6 the motor runs the same so like I thought something is up with # 6 Im guessing its that damn coil so what im going to do it swap the coil and a injector and see if it moves cylinders then I can see if its that coil!

John, isolate the cylinder. Once you have that figured out, ohm the injector. If the injectors check out fine, it's the coil.

As far as an instruction manual for the tech 1, it's easy to navigate.
