have you checked to see if your air filter or the cold air feed is blocked?
Nope.
But the filter was installed several weeks ago.
Besides, guys, this problem was right from the moment I bought the car! It had a lose of power on the full trottle and in high revs.
So, I think there may be two problems: blocked cold air feed of too soft pipe between air box and trottle body ....
But I set up yesturday a metal ring inside the pipe so it stoped to shrink and I've got a great piece of power. I felt in on the highway.... 8)
Last news: I got a cold air feed pipe from vectra C, it's look like bigger ....
Tonight will deinstall the airbox, look for different blockings, besides redestrict pipes inside airbox (thanks to HOW TO section).
