Engine/Transmission (1994 - 1998) What is the "star wheel" and where is it?

[swordfish]

I looked for a "star wheel" on the afc but I could not find anything that looked like it. I have my plate slid forward all the way and the afc housing too. My max boost is 35 psi and my max egt's are 12. I know there is more room for more fuel, so if I turn the star wheel will I get more? I must find the damn thing first.

On top of the AFC housing there is a threaded plug that uses an allen wrench to remove. Inside is where the star wheel is. This won't give you more fuel, it will just give you fuel sooner.

I know how to adjust star wheel, but what is the plate that you say you have all the way forward.



thanks Bill

If vehicle is still slow to accelerate or has too much smoke, adjust the AFC setting as required . To adjust, remove the large plug on top of the AFC housing (see FIGURE 7) using an 8 mm allen wrench. Take care NOT to lose the sealing washer under the plug. Removing the plug exposes a star wheel which changes the quickness of fueling response to boost. If acceleration is weak with minimal smoke, rotate top of the star wheel toward the engine a few revolutions. If vehicle has heavy black smoke on initial acceleration, rotate top of star wheel away from engine a few revolutions. Reinstall large plug with sealing washer and test drive vehicle again. It may take repeated attempts to get this adjustment set. If heavy smoke is still encountered with star wheel moved completely to rear position, go back to step 26, loosen AFC housing and slide it rearward a 1/16 inch, retighten and test again. Repeat until desired results occur.
