I have an I0360 with Airflow Performance fuel injectors that have been calibrated. Now have 300 hours and all has run perfectly up until a few hours ago I started to notice in the yellow on #1 on takeoff. I have since inspected and cleaned all injectors. There was no obstruction or debris. After test flight, #1 in the red but would come back in yellow and green when I reduced throttle. I then disconnected all injection line, used 4 baby food jars, initiated boost pump and all fuel collections were identical. Next swapped Alcor 86255 EGT probes between #1 & 3 and test flew again. #3 registered high and I then installed a new probe in #1 and reinstalled #3 back in #3. Test flew and #1 registered in the red on takeoff, would come down to yellow and green on throttle reduction.
Please let me know other suggestions to check. I generally run LOP and the EGTs are within 10* between high and low and CHTs are very close also (#4 highest where oil cooler is located). I have two PMags and they have been flawless to date. Engine has really run very smooth, starts easy cold or hot. Thanks.
