Good day I bought a nissan skyline GT250 v35 v6 it had a 190000kms on the clock when I bought it , it was misfiring I checked the plugs and coil packs and found one coil pack was damaged I replaced it along with all 6 spark plugs, oil , oil filter , air filter basically I serviced the car after I serviced the car I took it for a test drive and the car gave a jerk and the engine light came on does anyone know what could be the problem please help.
