Hi , i have an 03 astra turbo cab . When the engine gets to temp it hesitates at first through the gears. and once the engine management came on. havent done a long journey since.
Once it cools then the light went out and all was fine until 15 mins later and the engine warm again, then it stutters. struggling to find out whats wrong. i thought egr but im told it dosent have one and i certainly cant find one. hope someone can help.
