Time for a new service, where in Dunners would i send this baby to be worked on? In town is best but willing to go the distance.

Anyway, when it\'s warm there is no problems but sometimes when you first start it the throttle response is shaky, jerky at low revs.

I have not changed the spark plugs or the leads - it\'s 2000 bugeye jdm no mods, runs 98 bp fuel, using 0-40 mobil 1.

Should i change both? What else to do once there - i\'m told by mcleod it\'s a bit of work to get to the spark plugs but when i asked what else should i do once he gets there he says erm ... A tune up ... But then he can\'t explain what a tune up is ...

Thanks

Later stuff has a bit of a subtle stumble when cold but once its up to temp its fine sort of a safe I think. Unsure if thats what you mean or worse. I put up a thread asking when I got my V5 as my V6 forester was the same but everyone had the same issue in pretty much everything phase 2.

When\'s your cam belt due? As they get close to change time they\'ve stretched and the cam and crank position sensors can get a tiny bit out of time and can cause a miss.

Not saying it\'s the issue here but something to consider nonetheless. Happened to me.

cambelt\'s already been done. but the *&^% cheapie owner didn\'t do the water pump I think *sigh

anyway, so I gather head to sim\'s brothers, change spark plugs, and the cold cough cough jitter jitter is normal

Yeah come into work and we can do the spark plugs ... we can check the resistance of the leads too and if there may be one that has high resistance when cold causing the cough?? could be a number of things but thats a really good place to start. We aren\'t too busy tomorrow afternoon from memory so If you want to drop it in for an hour or so we could change them for you and check the leads .... or give us a ring 4771110.
