Ive' been trying to figure this out. Check engine light is on. I pulled P173 and P174 with my scanner tool. My air/ fuel ratio gauge is lean. I also am getting a rattle sound from the engine bay when the engine is under a load. I thought it might be a vacum leak. I checked all my lines They are good. New fuel filter and no missfires. The only thing I havent done is inspect the intake manifold. The car was badly niglected before I got it and it now has over 180,000 miles. I'm thinking I may need to replace the intake manifold gasket. any other ideas?
