I cleaned the MAF and retitheng the ground screws n the still came back on...what else would it b?...mayb a sensor?

Any ideas of why my car is doing that...and lately the car its been turning off all by itself so I shake the battery cables n it turns on does that mean that I have to change the battery wires?...the code in the computer still says primary ignition signal?

Ok bleed the brakes according to the sequence you mentioned. Except, mine has no LSV bleeder screw. I see the block where the 2 rears meet and join into one line to head forward, that's the obvious place for it to be, and I don't have one. Mine's 4wd too. Still get the codes, so I'm still thinking it's a short in the actuator.

Falcon if you can shake the wires and it works, yes, try tightening them up or replacing them. Pretty easy to eliminate that as a cause.
