2009 base coupe. Poor idle when hot. Mpg's falling. New oil, 4 Oz seafoam in crankcase, bottle of techroline in tank with 12 gals of 93 octane. I removed pcv hose but there is no pcv valve or is it under valve cover as some of these threads explain. What would be next step. Car has 95k miles. KBB is probably 5500 so not worth 2k repairs as some posts have suggested. Tha k you.
Carbon blasting Detroit Tuned and Helix both offer the service. Maintenance: Any type of service work. Need an oil change? How about a brake bleed? Carbon Blasting? Maybe you just need a new air filter. We can help. http://www.detroittuned.com/shop-services/
