Q: Vehicle check engine light is on - cannot pass smog test and stalls out - even when u press on gas pedal.

What all does tune up entail and approximate cost, Thanks!

My car has 136000 miles.
My car has an automatic transmission.

Sent to CS for billing question on how much it would cost for a tune up for the BMW to pass emissions test.

A tune up comes with cleaning out the fuel system and performing a fuel injection flush, replacing the spark plugs and wires, and replacing the air filter. Also, its suggested to perform an oil change prior to the emissions test to have a clean engine.
