My 2.2 T was stopped from many years.
At this time, I started it again but I find it is not really powerfull. The day I started it, engine did not want to go up than 5.000 rpm

Now, I ran about 400 miles at 90 MPH and it runs better. Yesterday, I reached 6.000-6.200 rpm in second gear, of course when engine warm.

Are these symptoms normal for a car that did not run for a while and that may need a new "breaking-in" or a "scrubbing-down".

or these symptoms are simply that the engine is worn ?

The engine is Weber 40IDAs carbed
