Hi.
My vito 112cdi 99v is running rough and when the revs hit about 3200 the engine revs will jump back violently. If you take you foot of the gas straight away the engine will keep going. If you keep your foot down it will cut out. I have had the injectors, the ecu and the wiring tested. The turbo and fuel pump also seem ok. The cam and crank sensors have also been replaced. The engine starts as usual but runs a little rough, the higher the revs go the rougher it gets and with much less power.
When hooked up to a computer, an error code reports cam / crank synchronisation error. There is 110k on the clock not guaranteed though.
It has been suggested that the timing chain has jumped a tooth has anyone elso heard of this happening? I thought timing chains lasted for ever. Wouldn't it be hard to start. I am reluctant to spend another £1000 on the van trying to fix it if its unlikely to be the answer. Any help would be greatly appreciated.
Thanks
Stuart
