06 Cadillac DTS p0203 (fuel injector 3)
06 DTS 172k miles
I’ve had an intermittent p0203 for about 2 years now. When it first started it was only in colder temperatures, below 40(F). The check stabilitrak light also comes on the dash when the injector is acting up must be connected somehow. This problem also only occurs once the engine is close to or at operating temperature. So far I’ve replaced the injector, injector harness, and a new ECU. Still having the same problem and I’m out of ideas. Thanks in advanced for any and all help
