check engine light is on and engine is sputtering as if it wants to knock off
Check engine light on 1993 Nissan Pathfinder
Read the codes on the ECCU if your check engine light is on. The codes will tell you what sensor is malfunctioning. Move the passenger seat all the way forward and use a regular screwdriver. Follow the instructions in a repair manual.
Could be misfire concern, could be fuel pressure issue, could be air flow issue. Needs a good diagnosis to find out what is happening. Good luck.
