Hi! Any good outcome of this issue a while ago? Kind of struggling with same issue on IO550D. After start, acts like it’s going to idle and then starts to die. If I catch it with elect fuel pump, it will stay alive. Have to do this for a few mins then it idles fine. But, when taxiing, adding power gives a pretty good hesitation and it has another go at trying to quit. Once it’s warmed up, it only hesitates when going from idle to about 1200-1500 for taxi. Amazingly, there is no hesitation or preponderance of trying to quit at all while airborne and at idle. Just wondering what you found out anything.
full disclosure here: this engine is on a c185….i just saw you had a similar issue with a 550 and wanted to pick your brain! Thanks!
