thanks ill watch the videos. also the codes that it shows are.
1. Too Lean On Bank 1
2. Random/Multiple Cylinder Misfires
3. Misfire Cylinder 1
4. Misfire Cylinder 2
5. Misfire Cylinder 3
I also wanted to add that i changed the fuel injectors on cylinder 1 and 4 as when we bought the car those were the cylinders misfiring. I have also checked the igntion coil packs for each cylinder and i have also changed all of the spark plugs and the fuel filter.
