I found B-12 at autozone and advanced auto had the seafoam.

Never mind. got out there and found the secondary cable disconnected. It's a bear to get in there with giant hands and even kinda hard to inspect. I have to take even the throttle bracket off to do it. Problem solved now. I must have disconnected it when I was cleaning.

Call me a fool, but how do you check the secondary cable? I'm pretty sure I'm doing fine with my secondaries, but I'd still like to check them. Where abouts can you locate it to check if it works, which I'm guessing is just by working the throttle up to 3750 rpms via underhood. I've got the haynes manual, so if there's a diagram in there you can relate to, that's fine as well. Thanks!

you are a fool (just kidding, you said to call you that). One the V-6, underneath the black oranmental plastic valve cover facad, there is an aluminum box IMRC (intake manifold runner control?). It was a DC stepper motor and gears in it. When your engine is somewhere over 3,500 I believe the motor will turn the gears and the gears (pull or push, I forget, I think pull) the cable. The other end of the cable goes to the lever for the secondaries which is located way down underneath the TB (throttle body). Just follow the cable. Good luck if you have a bad back and big giant hands. To reconnect the cable, I had to take everything apart and still could barely get it. Anyway, you should pop open your IMRC and rev the engine and look for cable movement, gear movement and lever movement as described above. Inspect your gears, motor and cable. I understand that you can lube your gears and clean your DC motor. You may wish to search more posts for guidance on that. I didn't do mine cuz it looks in great shape for 120k miles! I just reconnected my secondary cable to the lever. Apparently I knocked it off when I was working the secondaries to ungum them with B-12 or searfoam.
