Go GETTHE CODES.

When you go to limp, there is a code stored...simple.
Intermittant codes clear if they do not repeat...so you have to get it in situ...that's all. You have a computer monitoring for faults and it is there to tell you what it has detected, but you have to ask it... and it does not Guess......
You can guess and we can guess, but the DM does not..it reports what it has detected as not normal. ie, a Fault.

There is also a often over-looked ASR limp trigger if the tire sizing or inflation pressures are not equal...I always check that first b/c the module makes a 4 wheel circumference comparison .. [ rolling circumference is proportional to individual wheel speed]

These Flash codes should be available from pin #7 of the 38 Pin Diagnostic Interface Connector...and they are ASR related Faults.

lamp switch or engine speed signal or vehicle speed signal or closed throttle position
switch or safety relay in EA/CC/ISC control module
3 Right EA/CC/ISC actuator (left cylinder bank) (M16/1)
4 Cruise control switch (S40)
5 Stop lamp switch (S9/1)
6 Starter lock-out/backup lamp switch
7 CAN data bus signal from EA/CC/ISC, ABS/ASR, HFM-SFI or LH-SFI (right or left)
control module faulty.
