1999 Safari runs rough & code PO442
Evaporative Emission Control System Leak Detected (small leak)
I did a long overdue tuneup with plugs/wires/disty cap/rotor/fuel filter/PVC/Gas cap etc. I also found a broken vac line to the lower connection to the PVC valve and replaced the vac line.. The van idles ok but still runs rough when accelerating (but passable) I heard of fuel injector issues with the GMC Safari.. Any ideas? Vac leak?
