OK I have the 1.9 dohc roller motor 5 speed new ngk plugs wires filters ect. The engine has a slight misfire at low throttle low rpm usually below 1800 rpms. It lags power between 1200 and 1800 rpms can noticably feel the torque drop. Been doing it since I got the car 25k miles ago. Replace the throttle body gasket cleaned the injectors cleaned iac valve and replaced the map sensor. Not sure what else I have going on here. Maybe the timing chain is wore out and its causing the cams to offset at low rpm? Maybe some good ol ASE advice could help. Thanks
