having massive problems with 99scoob, car runs fine when first started up, and after a few mins wont rev past about 3000rpm, gradualy getting lower until its prety much un-drivable, have to pull over switch off for a bit then start it again and it runs fine for a few mins then same scenario, have just changed maf so i can rule that out, any idea's? im thinking maybe coolant temp sensor? could this cause this kind of behavior?

Could be any number of things, coolant sensor being one of them, crank sensor another, etc.

Save yourself some dosh from buying sensor after sensor by getting it to a specialist with DeltaDash (laptop ECU monitor). They'll have it tracked down in no time.

i enquired about this today at a well known tuning garage and they rekon the delta dash etc wont pick up anything that the ecu doesnt pick up in test mode? is this correct?
