Hi guys, I have 06 WRX with 65K miles on, which happened to stay outside over whole freezing winter here in Slovakia...
...and then a couple of problems started to occur...
The problem I would like to get your opinions on is related to the BOOST.
When I hit the throttle, it goes "boost - lower boost - boost - lower boost", simply the car is accelerating discontinuously. It also appears to have less power/boost than before the winter.
The car is also idling a little discontinuously, I can hear/feel small interruptions in engine run, first only sometimes, now much more often (every 3 secs).
There are NO mods to the car.
I have my turbo checked, it pressing only 0,9 Bar (WHY??).
I have new sparks (OEM), timing belt, all filters and oils changed recently, all OEM...
What can be the problem?
I will appreciate any advice!!
Thanks a lot guys in advance!
