Throttle Linkage Adjustment PICS????

[lfot]

Does anyone have a pictoral instructional on adjusting the throttle linkage on a 3.0 CIS?

I couldn't help but notice no one replied to your post. That's a tough one to photodocument, but the good news is that it shouldn't be all that tricky.

There's lots of adjusters: one at the gas pedal itself, on the ball joint which attaches to the plastic pedal, then there's the one down under the floor board, at the pedal pivot, next there's the one at the bell crank, attached to the trans, two there actually, another one is on the rod going up into the engine compartment. Finally there's one at the throttle body.

It's been a long while since I ditched my CIS for webers so I'm working from memory but I remember it being easier than teh weber linkage, and that's not all that bad. (not lik ethe MFI guys!) I don't want to steer you wrong, but make sure that when the pedal is to the floor, the throttle is all the way open (obviously), while at the same time making sure the throttle doesn't open completely before the pedal hits the floor (or you'll bend something). A lot of guys let the carpets get under the gas pedal after they adjust and that means they don't get full throtte, so set it up the way you like it, my carpets are long gone. Also try to adjust the linkage at the bell crank so that there's minimal slop in the pedal before you actuate the throttle body. That will give that snappy pedal response. Do give some slop there though or it'll tend to idle high sometimes, like when things heat up a bit.

Trial and error and a logical process are you friends. Good luck.

When I did mine a year ago, I assumed the adjustment at the pedals was correct. If I remember correctly, I was able to get the adjustment I needed from the two places by the transmission.

Also make sure the bushings on the top of the engine are in good shape. Mine were shot and prevented full throttle no matter how i adjusted the linkage.
