Hello i am new here and am not very good with computors and spelling so please excuse me. My problem is this... i brought a vectra c 1.8sri petrol over a year ago now and i always thought it was way to flat in the way of engine performance, i couldnt find any problems until yesterday when i decided to plug my scan tool into it and moniter the tp%, i couldnt seem to get it past 62%, i tried to load the engine thinking it might only be designed to give 100% in the taller gears? there are no fault codes...this would explain the flattness of the engine. IS this normal? is it a symptom of something else maybe like to much pressure in the cat?surely it would have a code, my s.t.f.t was -2.3% which is exceptable i was always thinking.....hhhm. Any help or ideas would b so much appreaciated... i would love to think i had another 40%throttle... brilliant..thanks people..
