Stuttering whilst cruising
Hi All,
At present I'm in the process of Auto VE'ing my Burb.
Whilst logging and cruising I noticed the truck stumbling/stuttering around the 2400-3000 rpm area and around 35-50Kpa.
If I give it a touch more throttle it's fine.
Is there a different table I should be looking at?
I've got my VE table pretty well tuned in in that range.
It happens as I'm just lightly touching the accelerator trying to keep on a particular speed limit...ie 100kph or 110 kph (normal freeway cruising).

YOU ONLY NEED TWO TOOLS IN LIFE - WD-40 AND DUCT TAPE. IF IT DOESN'T
MOVE AND SHOULD, USE THE WD-40. IF IT SHOULDN'T MOVE AND DOES, USE THE
DUCT TAPE.
IF YOU CAN'T FIX IT WITH A HAMMER, YOU'VE GOT AN ELECTRICAL PROBLEM.

Lean cruise?

No, I don't have the lean cruise hooked up Dave.

What does your throttle cracker add while this happens? Maybe, you could add a little or subtract a little air to see if that helps.
