CIS One more question please I need help
 

Thank you all for your replies.
If I unplug the o2 sensor the frequency valve will run at 60 lbs.

Will it work if I unpluged the valve and installed a fuel pressure regulator to run at 60% constant?

Thanks again

Your money is probably better spent by replacing your current fuel distributor with one from a 78-79 3.0, deleting the freq. valve all together. The distributor is the heart of the CIS system, and is a relatively accurate fuel pressure/metering system. Although you can try your idea...tampering with it can cause some serious drivability problems. I think the way that a fuel press. regulator works is alittle different from the way the freq valve functioned...not sure.
I too try to be a mechanic rather than just a parts changer, but in this case you may save yourself tons of headache by switching distributors.

Check your e-mail...I sent a long explaination.
Nick.
