My 2000 Seville STS has been having a slightly rough idle and slightly increased fuel consumption now at 115,000 miles. I was told to check the Fuel Pressure Regulator (FPR) using the procedure posted in the Tech Tips section. My FPR seems to be fine. I was also told to check the intake plenum, the rubber boot connecting the throttle body to the intake manifold. The plenum looks cracked to me, but I need some expert verfication. Please check the photos below and let me know if this is indeed cracked. What you are looking at are some closeups of where the plenum meets the hose clamp (the clamp that attaches the plenum to the intake manifold). Thanks In Advance!!!
