gs460 random major throttle hesitation.
A major throttle hesitation has developed in this car,that is so bad,sometimes when you put the pedal to the floor it doesnt want to accelerate at all. Feels like the car has a bout 25% power,it seems to shift very weird also,its like the car is trying to keep the rpms very low. Im not positive but it seems to occur mostly when the car is first started and still cold,or on very wet or humid days?it feels like the car is activating the traction control and the throttle plate is not opening all the way at wot?
Im using 5-20 oil. Maybe should go back to 0-20 oil. Cant imagine the sensors are picking up on extra drag from colder thicker oil at that close of a weight? No codes are showing when the car is checked out. anyone ever heard of anything like this?
