Re: **cold start up help**
Unless you get a total failure, there is no way for the PCM to measure the O2 for function. All it sees as data. The heaters fail, as in open circuit, then it triggers a light. Since you didn't have this problem before the injector install, I suggest you look there and the coolant temp sensor. If it is not working, the PCM will run it rich like a fresh start up
