GAZZUZZ:


Misfire is still there. Check spark plugs, distributor, plug wires, intake leaks, injectors, fuel pressure, and replace the faulty O2 sensor indicated in scan.

You will need to change mechanic that has the appropriate diagnostics equipment to help you get to the bottom of this issue.
Intake leak diagnostics will require a smoke machine for detection and fuel pressure will require fuel pressure tester .
After performing all this test and still there is no headway then u will need to go for compression test.Compression test will indicate if there is no leak of compression that is enough to cause misfire in any of the cylinder.
If you are in Lagos and you require the service of a professional mechanic that can perform all this diagnostics test for you .Call autologic @ 08061166316

ZIMDRILL:


1st clearing the code doesnt help if you havent found out what is triggering the code

since you change few things with new ones i guess the problem on an electrical somewhere wires etc

an not sure of the car specs whether has ignition coil or distributer try to focus that like Gazzuzz said check distributor, ht leads etc
