My city steermatic vtec, is jerking during accelerating from low speed, and appears to lack smoothness, feel dip in power momentarily. Anybody can suggest best fix mechanic/electrician. Have tried tuning, check by computer diagnostics only shows o2 sensor issue. Checked coil, plugs, changed valve body, end engine check light on since replaced with kabuli transmission. Plz guide me to possible fault or best workshop/mechanic to get resolved. Am deeply stressed as have been messed by 3-4 different mechanics and nobody seems competent to diagnosis and fix
