Yes... Vehicle is a 1990 with no mods or parts from other vehicles. The distributor holds no vacuum, removing the hose does nothing as it is basically a vacuum leak at this point. I tested using a tee on the distributor line connected to a vacuum gauge... The gauge did not register any vacuum, when I removed the tee and connected the gauge to the vacuum port on the driver side of the throttle body I got 5 in/hg at idle and 14 hg under light acceleration... I believe this is fine since that's a ported vacuum port. This is how I deducted the diaphragm is busted.Just to confirm (despite the title of this thread) currently the vehicle is a 1990 Tracker, all stock, and nothing from any other vehicle, correct??
I believe that the distributor should hold vacuum for about 30 seconds, if the diaphragm is ok. It doesn’t??
How do I remove this diaphragm? I tried removing a screw holding it but it didn't come out all the way, like something else is holding it besides the screw...
