Comment 2
Customer Concern: Engine is setting misfire codes. Has good spark and have swapped the injectors around. Compression is normal. Tests/Procedures: 1. Connect a vacuum gauge. If the needle is erratic, check if an exhaust rocker arm has fallen out of place. 2. If so, carbon build-up on the valve is the likely cause. You need to remove the valve cover which number 5 is and check valve train. -
