Got a 93 fd and ive changed a few things on the car like the metering pump, wires,spark plugs,and throttle body gasket. The car runs and drives but has a little issue when it warms up,the car starts to idle erratically up and down like a vacumn issue ive looked everywhere except underneath the intake manifold.Check engine light is not on just the abs which brings me to another issue if the abs light is on is my abs pump bad.Really im assuming its bad cause theres not to much to the brake system and top of the abs pump looks wet.Is there anyway i can diagnose the abs light any help would sure be apperciated thanks !!!!!!!

 

The ABS light could be on because of a bad unit, but try checking the wheel sensors, it could be that one of them is dirty or damaged.

 

on the vacume leak you can spray some break cleaner or carb cleaner around the openings on the intake to find a vacume leak. The idle will change alot if you spray on a leak. Just a fast way to know....

 

aperciate all the advive thanks a alot but on the wheel sensor for the abs. How do i know if its bad is there a way i can check it ^^^^^^^
