Narrative:
After advancing the left thrust lever slightly for southeast taxi out, the itt gauge spiked instantly to a high reading. No other engine gauge correlated they were all normal. When I brought the left thrust lever back, the itt indication instantly went back to normal. A second attempt had similar effect along with an engine flameout caution. I immediately retarded thrust lever to fuel shutoff, so I did not allow the fadec any attempt at restart. I now realized I was in aircraft XXX which has special procedure to follow for warm-up. I had not remembered this. I checked the mdc current faults section and found no recorded faults. Thinking I had induced the problem by not following the protocol for that engine and, more importantly, thinking the itt #1 reading was an indication problem only, I then restarted the engine and found no other problems with it. I then decided it would be ok to fly since I had brought on the known problem. The subsequent flight was completely uneventful. I did, however, look deeper into the mdc and found the record of the itt readings. I realized then that maintenance needed to be informed as soon as possible, so I telesised them in-flight and alerted them to the inbound write-up in okc. I've learned not to make decisions that maintenance should be making. If I had found the mdc record in ord, I would have called maintenance control prior to flight. This mistake will not be made by me again. Sorry.

Title: FLT CREW OF CARJ MISINTERP INDICATIONS OF ENG STARTING MALFUNCTION. RESTART ENG AND DEPART VICE OBTAINING APPROPRIATE MAINT ACTION.
Narrative: AFTER ADVANCING THE L THRUST LEVER SLIGHTLY FOR SE TAXI OUT, THE ITT GAUGE SPIKED INSTANTLY TO A HIGH READING. NO OTHER ENG GAUGE CORRELATED THEY WERE ALL NORMAL. WHEN I BROUGHT THE L THRUST LEVER BACK, THE ITT INDICATION INSTANTLY WENT BACK TO NORMAL. A SECOND ATTEMPT HAD SIMILAR EFFECT ALONG WITH AN ENG FLAMEOUT CAUTION. I IMMEDIATELY RETARDED THRUST LEVER TO FUEL SHUTOFF, SO I DID NOT ALLOW THE FADEC ANY ATTEMPT AT RESTART. I NOW REALIZED I WAS IN ACFT XXX WHICH HAS SPECIAL PROC TO FOLLOW FOR WARM-UP. I HAD NOT REMEMBERED THIS. I CHKED THE MDC CURRENT FAULTS SECTION AND FOUND NO RECORDED FAULTS. THINKING I HAD INDUCED THE PROB BY NOT FOLLOWING THE PROTOCOL FOR THAT ENG AND, MORE IMPORTANTLY, THINKING THE ITT #1 READING WAS AN INDICATION PROB ONLY, I THEN RESTARTED THE ENG AND FOUND NO OTHER PROBS WITH IT. I THEN DECIDED IT WOULD BE OK TO FLY SINCE I HAD BROUGHT ON THE KNOWN PROB. THE SUBSEQUENT FLT WAS COMPLETELY UNEVENTFUL. I DID, HOWEVER, LOOK DEEPER INTO THE MDC AND FOUND THE RECORD OF THE ITT READINGS. I REALIZED THEN THAT MAINT NEEDED TO BE INFORMED ASAP, SO I TELESISED THEM INFLT AND ALERTED THEM TO THE INBOUND WRITE-UP IN OKC. I'VE LEARNED NOT TO MAKE DECISIONS THAT MAINT SHOULD BE MAKING. IF I HAD FOUND THE MDC RECORD IN ORD, I WOULD HAVE CALLED MAINT CTL PRIOR TO FLT. THIS MISTAKE WILL NOT BE MADE BY ME AGAIN. SORRY.
