new to this site, got a 02 gt stang, service engine light on, code reads fuel temp sensor circuit range/performance, is this a specific code for o2 sensors or a generic code for something in the fuel system, the engine will not start unless you lay on the starter for about 5 seconds when cold. at idle there is a noticable lag or almost stall when at a light, any suggestions are greatly appreciated

 

Have there been any mod's done recently to the car?

 

no mods, all stock, also code p042b poped up today, thinking something related
