1991 Pontiac Grand Am Value Leader 2.5L Poor Idle Quality, Cuts out
Posted to GM Driveability on 7/30/2004 6 Replies

Plugs and wires changed, have checked coil packs, crank sensor, TPS sensor, ign module, EGR valve. Unplugging vacuum from EGR & capping hose improves situation but not totally, & instigates check engine light & EGR code.
