Ok changed cam cover gaskets a few weeks back and have zero leaks to my relief. Put the car back together and now have a slight surge when pulling away and also puffing from the exhaust. Retraced steps and everything's refitted correctly..
I did the Pcv system and changed spark plugs a month prior to doing the gaskets and the car was fine..now suspecting spark plugs or coil packs, if I haven't torqued the plugs correctly could this happen? They are nipped tight and not loose. Can't get under the bonnet until tomorrow evening so gathering info.. thanks in advance
