PARTS GUY, December 25, 2012, 13:13MasterCustomer 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.
