Have a slight problem with what i think to be the engine on my 54 plate Astra SRI (H model) 1.8 16v. Its when changing gear beit at normal RPM or when taking it to higher RPM the car seems to feel as though it has no power for about a second then kicks in. Kind of like a jolt each time a change gear.
Ive changed the oil and i think the plugs are ok. I called Vauxhall to try and get a fuel filter because that hasnt been changed for a while but they said the new shape astras dont have fuel filters????
The car generally doesnt feel as quick as it used to. Any ideas?
Also if i were to replace the spark plugs again (which i think i will do) what is the correct torx for tightening them? also brand?
