Can someone tell me which engines are bolt on fit in honda city idsi 2004 vario? Mine is having issues like engine giving smoke very poor Idling(changed plugs, coils, full tuning done) clicking noises when lifting foot off accelerator. Very low pick and with ac on it takes a lot of accelerator to reach even 80. When the plugs were being changed recently back side plugs had oil on them and one of the plug refused to open so it is left unchanged.
