2,4 JTDM - Engine Noise Between 3200-4000 rpm
I have noticed (while driving) a noise which is coming from the engine between 3200 rpm and 4000 rpm. Noise is evident when the revs come downs (when accelerator pedal is released). It is hard to me to describe sound, but it it is like rubbing metal noise. It seems that that does not affect car performance!
When I rev engine (with stopped car) I here different noise and it seams that it is comeing from front of the engine. I'm pretty sure that sound is not coming from belt.
Has anyone experienced a similar problem? Do I have to be worried and go immediately to mechanics or wait till regular service which is coming in 4000 km?
Also for last few thousands of km I'm noticing some vibration on idle (intensity is not always same), and strange behavior on aprox. 2200 when trying to keep constant speed - car stars to shake, and rev meeter and turbo pressure meter going up and down noticeable. When I try do accelerate in such situations sometimes car do not want do it. This usually happens few times in 1000 km.
I do not have any errors on dashboard or warning lights and I'm using regulary fuel cleaner!
What I can expect from that?
