This is the way to check out
the FV,
Frequency Valve,
Scope it, Not the best
but you get the idea.
|
This is a great idea.
Regular spring from
Home Depot, stretch it out and
clip off ends, goes in fuel
pump
pick hose to keep it from collapsing.
|
Idle adjust screws
should be snuged
down. DeLorean uses an
idle speed
motor/ECU.

To make adjustment. Get,
engine hot, unplug 02

Plug 02 back in and test idle.
May need to do more than
once.
Air flow adj. reference.
Counter to lean &
Clock to en rich

Full throttle switch location.
This maximizes
gas flow via
the frequency valve when the

If
you car is hunting or seeking at idle then here is what you
do.
Get a 3mm long handle Allen wrench, and with the car hot and
the 02 sensor unplugged adjust the fuel mixture screw counter
clock wise till the car starts to stumble and wants to die.
Don’t make any rash moves if it dies, it will start right
back up. Now, once you have reached the bottom or lean
adjustment then adjust the fuel mixture screw clock in little
baby steps till it starts to smooth out.
It may not be perfect but don’t adjust to much clock. Now
once that is done and you think it’s about right then plug
the 02 sensor back in and go drive the car 15 to 20 miles. Impurities
that have collected on the 02 sensor and plugs needs time to
burn off if it's going to. Short hops wont do it.
Be sure to cover the screw hole up with something because
it’s a vacuum leak.
Once you have driven the miles on the road come back and see
how stable the idle is. If it’s still not as perfect as you
want then you can re-adjust following the steps above.
Then adjust the idle to about 950 after you have it
about as stable as it will be. Plugs , wires, cap,
rotor any could cause a short hic cup in the idle.
let
me know if there is any thing else.
