Hello all,
Got a problem on my honda civic 94 ex d16z9 M/T. Car is stock.
On high RPM revs (5k and further) while throttle is fully opened, there's a high pitch whining sound (like sucking/pushing air through a tiny hole) comes from the car. I don't really know where it comes from (intake/exhaust).
Second problem which I think has a relation to the first one, is unstable IDLE (playing between 600-800RPM), and looseing some power at the high revs range.
Any ideas?
