Yeah, that alone will do it the world of good. Tho what you could try and I did this with mine today is take the plugs out and pour about 500ml in to each of the combustion chambers and left it to stand (about an hour while i changed the oil).

With the plugs still out turned the engine over for about 10 secs. Tho as pretty as the fountain of redex shooting up I should have put a towel to stop my engine bay getting covered!

Put the plugs and leads back in and the amount of crap that was thrown out was shocking!! Worked a treat as there is no carbon at all in the chambers and my injectors are gleaming!


I did squirt a load of spray injector cleaner into the throttle body and redex in the take to make sure.

Give it a bash, worst that can happen is it wont start!
