Five days ago I had my radiator replace as well as the timing belt and got a complete tune-up, but my car is not running well. I went back to the shop and two new codes came up - the oxygen sensor and the Idle Air Control Valve. The mechanic says these two are not related to the work that was done...and says it will be an additional $800. Now my car is stalling at red lights and the engine is vibrating at every stop. Any advice? I can probably replace the Oxygen sensor, but I don't want to touch the IAC valve. Is there a chacne that these two thing only need to be adjusted and not replace?
