hello, new to the site. 06 xb12ss. problem, at proper operating temp, under normal to heavy load, usually after the clutch is released to shift up, hot or cold out side, the engine will cut off clean for a second or two then back on with out missing a beat. at the same time the check engine light will light up fro 3-5 seconds then back off. hooked up to spy found no codes. full diagnose of everything spy can do and nothing. visually inspected all wires head to tail and found no wear or rub marks or looseness.if i unhook the batt or pull the 30a fuse for the night, the next day it runs fine for about 50 miles then starts acting up again. sucks when it does this going straight but kinda driving me crazy when it pulls this crap on corners. please help, can not afford to throw parts at this and not get results.

In the ECMSPY\Diagnostics tab, is your White Cable (just under Active Muffler Control in version 1.12.27) set to on or off?

If on, try switching to off and take for a test ride.

I had the same problem a while back, once every few tankfuls usually while going straight with steady throttle at 40-60mph, but once or twice while accelerating uphill. It's like getting kicked in the nuts. Luckily never happened mid-corner.

Since I made that change in spy, it hasn't come back once.
