My check engine light is on an solid burning. We have replaced the carbon canister, the EGR Valve, EGR Modular(or Solenoid) and one other part I don't remember what the mechanic said it was but some kind of control valve he said we replaced the whole emissions part of the car but the check engine light is on again. Where do I go from here?

You have replaced the most common emission failure problem parts on the Camry but heater circuit for the Oxygen sensor is a common failure. I don't know about the east coast but on the west coast many large franchise parts stores will check fault codes for free in hopes of selling you a part to fix the problem. Your car has On Board Diagnostics level 2 which has a 16 pin socket under the dash, a scan tool is plugged in and codes like P0300. P0420, P1116 are displayed representing the area in which the problem lays. If you can tell us the trouble code we can suggest the a fix to the problem.
