Hi all and apologies up front if I cover old ground. I recently bought an '03 petrol sport for the well documented 4 wheel drive benefits at this time of year. Very clean and well priced and only 85k so after a reasonable test drive I bought it. Daily driver is a Merc 320 so it obviously it felt very different and not very powerful but I initially put this down to my driving style and possibly not letting the engine rev out. However after more miles I think I may have more of a problem, the car is very reluctant to rev, even in the intermediate gears, on the flat in 3rd at 2500 revs foot hard down and progress is very slow and uninspiring (almost feels like the brakes are holding it back ) up to 4500- 4750 when the engine management light starts to flicker, back off and it goes out??? I see some posts about old/dirty oil clogging the VVT mechanism but I can feel the step at about 2250 presumably the v-tec kicking in I spoke to the dealer and although he is sympathetic and assures me he can sort it he has no idea what may be causing it, I could do to see him armed with some idea of the problem and what remedial work may be required I work away and will not get the car back to him until the weekend, minimal use in the meantime. Can anyone give me any guidance?
