Check the egr and clean the carbon out from it under neath, check and make sure the diaphragm does not leak. Another thing take carburetor cleaner and spray along the intake & head, the TBI base gasket, and anywhere there is vacuum. If there is a leak, the rpms will pick up. Snug up the intake, replace TBI gasket, replace EGR valve, ALL IF necessary.
