having trouble with my altezza once i hit 5000/5500rpm in every gear the car splutters and runs like s@3! at this point and the engine management light flashes on for a split second anyone have any ideas? When I rev the car in neutral it does the same but this time at around 6000rpm's
Probably VVTi then if its not the MAF or coils. You should be able to get an error code out of it if the engine management light has come on. You find how to access & read them if you search this forum. I'd also search VVTi issues as well, has been covered a few times round here.
