I have a 97 KIA Rio 2.0L.. After I did an oil change and replace spark plugs, its running slight rough. Idle drop down, has lost power when accelerating, and engine lite came on. Need answers please
double check plug firing order. Is the plug gap correct? You can swing into auto zone and they'll tell you why the engine light is on.
You probably have a loose timing belt and worn out tensioner and slipped one tooth. This could fry your Catalytic a bit. You'll get P300 codes of more than one indicating sudden multiple misfires when you should just get one at a time if at all.
