As i took the car back home, i i ran it a few times till about 130 miles , i encoutered the problem once and was very disapointed. later at the evening i did 2 0-190 mph runs , and the problem is gone , 1.4 bar all the way to 190mph I guess afterall it was a fuel problem as i guessed , and the cars tank still has some residue of the low octane fuel left so thats why it acted like that breifly today. i'am going to fill the car with high octane pump fuel and we i will do a few runs and let you know. This is a lesson to not let a gas station attendant fill your car with gas, and if he did double make sure that he is putting the right gas !!!!! Good thing it was an easy problem to solve...much better than something wrong mechanically

This is good. But sometimes the sensors would start working good for me and then go back to the bad habits later.

But hopefully this will not happen to you.
