Hello, I'm new here. I recently bought a 99 beetle 2.0 gas. Cel was on when I bought it, but it was running great. 2 days later it wasn't. Multiple misfires on 2, 3, and 4. Also the fuel trim is too lean. I bought a bunch of parts and had my dad put them on and it seems worse. The parts changed: plugs, wires, coil pack, fuel pressure regulator, 4 fuel injectors, mass airflow sensor, and the upstream oxygen sensor. This is my first car and after putting all of these parts on, my dad is at a loss. He even tried spraying carb cleaner on all vacuum lines and connections looking for a vacuum leak. Any help will be greatly appreciated as now I am broke and still driving my dads truck.
