MPFI Idle adjusting screws.


Recommended Posts

Hello there is two screws on my carb.

Is there a basic setting on these?

 

And now to the annoying part because when i unscrew the idlescrew on the back side of the carb it jammed.

Resulting a broken needlejet and broken threads in the carb body.

Luckily i have a spare carb which i used.

Unscrewed the same fast needle jet and the same spoob happened again.

But this time i got it out alive and noticed the rubber on the needle was loose.

 

Is there a better way to make this work or do i have to buy new needles?

Use the vertical one to set base idle to 700 for manual and 800 for auto w/engine fully warm.

The horizontal one only adjusts fast idle when the FICD(fast idle control device- a solenoid) is energized.(AC on)

 

Dunno about the needles
