Went out and bought an Apex'I S-AFC and installed it...leaned out the idle by 28% and everything is good! The A/F Gauge sweeps back and forth again as it should.

My idle must have been REALLY rich to be in need of a 28% decrees in fuel. I tried 25% and it still stays mostly at rich and 30% stays mostly at lean..so 28% was the magic number.

Thanx to the guys that helped me out.

 

nice... Is there a reason your running so rich at idle? Did you raise your fuel Pressure?

 

Man I need one also, where did you get it? how much?
BTW-my B&M fpr sucks *****

 

The reason Im running so rich is because supposivly the aftermarket cams do not create enough vacuum at idle (or something like that)
I do also have a B&M fuel regulator which has been working great for montehs. I plan on using both to tune..as I have heard that if you go +15% with the S-AFC..the ECU throws a code...so I plan to raise the fuel with the B&M and then decrese it in areas necessary with the S-AFC.

I bought the unit locally for $299 new
