Question about 2003 Pontiac Grand Am
Let me get the problem straight. You replaced the thermostat with one not designed for you vehicle. And now you have a code. But you didn't have a code before. In my experience 99% of the time you need to look at the last work done which in this case was to install an improper thermostat. Yes it could most def be an air pocket. Or it could be the FI system is thrown off by the t-stat that takes longer to open. This is not like cars of old. The FI system expects to warm up in a fixed amount of time. I'd install the thermostat that the FI designers were expecting to be in your car.
