I have a 2002 Mustang coupe, had my cats cut off and instaled two flowmasters. After one month the "service engine soon" light came on. When they cut the catalitic converters, they left the emisson sensors in place (they are located right before where the cats were). The car runs great, found no problem so far. I checked the owner's manual and it says it could be:
- Problem with emission control system, or
- bad quality fuel (which is not), or,
- Fuel cap is open (not my case),
How can I check the emission control system? Does anyone know what sensors and what parts I need to check? THe car is almost brand new, so I guess there shouldn't be any defective parts.
How can I shut down this damn light??
