The P0128 DTC is common if you live in a very cold climate area but if in a warmer weather area a problem. It means the PCM module has detected that engine warmup time via the ECT sensor is taking too long to properly warmup. Engine temperature rise too slow.
In most cases it is a defective thermostat but could also be a an ECT monitoring issue.
What does your temperature gauge at the IP read after sufficient engine warmup time?
