Look inside the air filter box? Is the cold / warm air filter flap valve inside the air filter box stuck to pre-heated air from the silver hose connected to the exhaust manifold heat shield?

Pulled the vacuum hose between the fuel rail CPS to the air intake port? Any gas leak?

You have socket 2 faults code for fuel injection, emissions. Any fault codes on the socket 6, ignition?

Check grounds, engine control wire harness connectors .... bad (loose, corroded) grounds can make the engine control system form a rich engine idle and running. Battery to engine & alternator to engine.

Exhaust unions are good? Specifically any exhaust connection upstream of the catalytic converter. The union at the header pipe output to the catalytic converter is a feeble one on normally aspired.

Probably not Turbo, no?
