I had my service engine light come on with a code for bank 1 on my cats, temprature code. I dont have cats, so will i need to replace my front O2 sensors, what could have caused it, any suggestions? TIA

Usually,cleaning them will give you about a week or so, replacing them will give bit longer. Your best bet is deleting them with LS1 edit programing.

Damn wish I had Alldata at home but unless you have a heater circuit problem or slow switching your cats or rear 02's aren't your problem. If you have headers that is what is causing your problem,delete your code and see if it comes back.

P0125 Engine Coolant Temperature [ECT] Excessive Time To Closed Loop Fuel Control

has it been realy cold outside? i threw a code when it was real cold outside when i went to the mall one day. it was probably because of the lt's and extreme temp outside that kept the o2's from heating up when they were supposed to.

why do you have sims out back?
