2001 Cadillac Seville SLS 4.6L Poor Idle Quality, Misfire, MIL Lamp on
after start up the egr valve opens for about 10 seconds causing the car to run rough you can watch it open on the scan tool the valve isnt the problem i tried another thinking maybe it was weak it does not have excessive back pressure either
