2.5 v6 156 acceleration and top speed Q.
I have recently bought my beloved 156 2.5 v6 model 1998, although evrythng is crisp and I have made sure I didnt buy a faulty car (garage inspection etc.), there has been something bothering me ... the engine is fine runs like clockwork untill it reaches 4200 rpm when it suddently feels like it reached a hole and the raw strength from just before, falls!! I have also tested it on the motorway (autobahn) where on paper it is supposed to do 230 km/h but only reached 210 ... I have been reading some forums which suggest that the MAF is responsible for the lack of torque, but opening the air filter and analysing the air flow meter, I coudnt find any defect! If it is faulty would I b able to see? or how can I test to know that the maf is the actual problem?? What else could be resposible for my high rev problems??
Thank you to anyone helping me here!!!
