Stabilitrak off, check engine light and reduced engine power light after kick down

Hi mates,

I am driving GMC Envoy 2007.
Last night was rainy one, I stopped at red light and when it openned, I hitted acceleration then suddenly all power jerked, and got "StabiliTrak OFF" in the DTC, reduced engine light, check engine light and traction control service light and the car started shaking on low RPM, then drove it slowly back home and switched it off for 15 secs(as it is recommended in one of the sites) then started again and all alrams and messages gone,except "check engine" alarm.
then parked all night and today morning strated it and still having this alarm, but afternoon, it disappeared!!!!
Do you have any ideas what d'Fck happened??!!! Any suggestions?

Thanks,
Iyad

the reduced engine power is usually associated with the gas pedal sensor.
but since you also got the other messages.... hmmmm

I don't know if you have a local Autozone or Advanced Auto parts store where you are from, but they can read your codes for free. I would do that and then write down what codes it is throwing and post them on here and do some research and find out what the codes mean.

I am new to this post, just found it after researching my vehicle.

I just had a sensor replaced in the Gas Tank due to the recall (my gas gauge stopped working) And about (2) days later my vehicle starts having the Reduced engine power light, SES light and the stabillitrac light,

The codes popping up are P2135, P2138, and P0641. I had no problem with it prior to having the sensor in the tank replaced. I have 86,848 miles on the TB.
