👍Hi sir, my Triton 2015 1N14 126000km RPM at idle 650 and target value is 650 RPM, when I rev the engine and let go the rpm drops to 625 RPM and feels like it is going to stall and then comes back up to 650 RPM and idle there at 650 until I rev the engine again. When in P or N and the AC is on at idle and cycles between ON and OFF RPM goes to 900 drops to 625 and the comes back up to 650.
Has a little rough idle but when driving it is smooth and responsive. No DTC, MAP sensor and hose good, MAF good, throttle body good and clean and replaced recently, EGR test using OBD2 Actuator test. When driving and AC is off when coming to a complete stop same thing happens down to 625 RPM. Any clue or advice you can help me with would be much appreciated 🙏.
Thanks.
Rich

Try to clean injectors sir if you have injector cleaner for diesel engine if you don't have it remove injectors for calibration, I had video for injector cleaning for diesel engine.Do compression test too.

@@autofixgarage5438 thank you for the reply, sorry I forgot to mention I did do injector cleaning with Liqi Moly Purge cleaner .
and replaced fuel filter, compression is good. I have a guess that it could be EGR valve stuck open, what do you think, is it a big job on this engine and you have a video on cleaning testing EGR?
Thank you.
