So started my 2007 Tahoe and pulled out of parking lot, my stabilitrak off message came up on dash then went off...driving down the road fine then when pulling into a parking lot about 10 minutes later truck was sluggish and didn't want to see to turn, then engine check light came on. I parked, went into the store for about 10 minutes came out to start it up... it's in Park...but jerks forward...scared the mess out of me. Was able to back out of and take off, not sluggish at all this time, but engine check light is still on. Had windows down to listen for any noises but engine was quiet. Pulled in and parked without any more issues.. this happened one other time several months ago minus the engine check light but then after it sat for a little while everything ran perfectly until today.
