Dealers near York, PA that KNOW how to do the cold weather 3cyl and idle reflash?
Fired the truck up this afternoon.
NO parking brake, just waited for the Grid Heaters to cycle, and hit the key.
Raised to 1200RPM after about 5 seconds of idling.
Did mine with the DRB3 Saturday,,
I started it up Sunday temp was 30 degrees about 15 seconds after start up the idle starting going up to about 1200,, BUT NO 3 cyl drop as far as I could tell,, Today I started her up,It was 8 degrees and it did the same thing up to 1200 RPM,THEN a Hellish noise WOW I thought the engine was going to spit a Rod out, Then I realized it was the 3 Cylinder option kicking in, Warmed the truck up in no time,,,, I Like It
High Idle kicks in 32 degrees or below The 3 Cylinder option kicks in at 15 degrees or below.
