Your EGR valve may be clogged. Purchased on eBay or Amazon for $67.00--max 1hr labor--Most common reason: throttle body requires cleaning--remove air box chamber atop throttle body--you will see two valves--open throttle--you will see gum, varnish, black sticky mess--spray throttle body cleaner--clean until bsm is gone--you Caddy will run better--last replace the $5.00 pcv valve--check out Seafoam treatment for throttle email@example.com Almost forgot--check the hose connected to the engine valve cover and air box--if cracked, replace first

Hi, Have no answers...looking for same answers for my Cad DeVille. Changed tensioner pulley, idle pulle, motor mounts, two oil coils, spark plugs/wires in past 5 weeks. Now they think it is the fuel injectors. Did ou solve your problem. I go for all servicing and oi changes so at 174,000 miles and recent repairs there will be nothing to do on the 190K servicing but it is idling very roughly and driving roughly.....
