James, My car has an Odyssey PC925 battery (age unknown, but I've had the car 18 months), & a Ctek permanently hooked up. I think I'll buy a new battery anyway, & take your advice re the charging regime. I'll also try some MAF cleaner, as the MAF seems not so easily or cheaply available &, on reflection, the cleaner is worth a try first. Will also check fuse & wiring connections

Re the battery, some people recommend a Tayna Red Flash 750, others the Odessey PC925 (Extreme?). Any views here either way?
