I did the carbon clean. Plugs wires coils and new pigtails on the coils. Nothing has changed I ordered a pcv valve. From reading other post I found out mine is bad. I also ordered some injectors there on the way. And ideas would help. I did a compression test on all cylinders and help 180psi on each for 5min. All good there.
ok missfire on cylindeer 6 carbon cleened injectors replaced 1 removed intake manifold cleaned and removed flaps still get engine manigement light on when i boot it
any ideas
Generally the list of things you want to look for when you get missfire codes.
1st check the fuel trim data in vag com
2nd if you didn’t recently do a carbon clean do one
3rd inspect the intake manifold itself to see if the flaps are broken
4th and this should be done no matter what the top 3 are. Your going to need all new injectors or serviced and cleaned injectors.
The injectors in the 5.2 motor are not lifetime injectors
