H22 engine loose power from 2k rpm till 3k rpm

So here is the problem. Car rews ok when staying , but on the move its stucs like no air but after 3 k rpm puls like a beast. Is that ignition problem? As fuel sistem all good now. I started from it to check. Ecu shows nothing , only egr valve or smth. Comes on on high rpm sometimes.

Dont know what to check. Adjust dizzy helps but not for long. I start thinking its something with wires , or ground wires to engine head. By the way its h22a5 with obd1 convertion and p13 jdm ecu. Dizzy from h23 eudm obd1 engine.

Ewerything what in your mind will help buddys

Ps. Car become road legal after 3 years staying in garage

is it about 3k when the bypass valves open? If they were staying open (not closing at low revs) it would have too much air at low revs and that would cause similar problems to what you describe?

That's me stabbing in the dark, it must be said!

After the difference made to my car by fitting a new air filter, I'm with Lude-Dude - check that out first.

yeah does sound like a bogging issue but the symptoms are so vague

That's true enough, it could be one of a thousand things

Air is ok. Maybe throtle body sensor? As im using it from h23. Adjusting dizzy helps but till you park car for a while. After start again the same problem. Ecu reseting itself?

valve timing cam timing it really could be loads of things it could just as easily be a bad plug or leads or the coil in the distributer these things need to seen firsthand

Just changed distributor cap and leads to magnecore kv85 , nothing changes. Probably will buy new distributor. Didn used timimg gun as i think there is no point , as at next start old setings are gone. Need to adjust again for good ride. But there is a problem with dizzy for sure in my opinion.
