Hi all!

My 2005 1.8 vectra breeze is losing power occasionally when I set off. It happens mostly in first and sometimes in second gear and I think it happens more often when I push the accelerator fully. It seems to dip in power for a second and then pull forward as if I am clutching badly. I did the pedal code read and got code 0136, but I have no idea when this code was stored or if it would affect my problem. Any help would be grateful. Thanks!
