Just got my own Mod 4 DTC 61...
 

I just got back from the store - quiet Sat early AM ride.

On the way back, Closed Loop - I went just under full hammer, and got SES for LESS THAN 4 SECONDS. I had to let off to get my turn.

Pulled ALDL, and got H 61 mod 4. The mod 1 H72, and mod 4 H 42, which lit up earlier this week, did not light up in ALDL.

HAS TO be a DEFINITIVE clue - that it went out immediately when I let off. Could this be electrical? This is the 3rd DTC 'Intermittent' - 2 ECM, and 1 CCM this week.

(not trying to boost your thread here RT; I'm guessing your 61 is mod 4 also??? )
