if there are no air leaks it's most likely ignition related. Might just need new spark plugs (NGK BKR6E11s are easy to get, and cheap - you just need to gap them down to .8-.9mm) If it has an aftermarket blow off valve check that the vacuum line is connected and that there are no leaks between the BOV and the intake manifold in the vacuum lines. |

Or you could just buy BKR6E's which are already gapped to 0.9mm. Justin...l |

it's extremely rare for those to be in stock anywhere though, so you end up having to order them in. Most engines run 1.1mm gap. |

Really? wow. I guess the two boxes I bought off the shelf a couple of months ago from precision auto spares in bondi must have been really rare then. ordering in for most auto shops means a couple of hours to a day or two at the worst. it's not like it's some obscure plug for a lawnmower or something...

good buy! so, if the shop stocks BKR6E9s, get those - otherwise it's easy to gap down the 11s, which in my experience have been a lot easier to buy on the spot. I had a steel ruler which worked perfectly as a gap gauge 
CJ8s for almost all lawnmowers are available at every servo, supermarket, and hardware shop
