1997 Chevy Astro 6 cyl All Wheel Drive Automatic 71000 miles
My son had to jump the van (he left the fog lights on). Heard a snap. Bought a battery. Now engine starts, runs at high RPM for a few minutes, then " bogs down" and dies. Can't drive it. Fuses OK, going out to check the vacuum lines. Ant ideas? PCR?
