After upgrading to catless downpipes, I started to
see more smoke than usual. I started to get misfires,
so I changed the coil packs, spark plugs, and
injectors. I even changed the hpfp, and ecu to ms.d81.
I'm misfiring from cylinders 4, 5, and 6 - 6 has a
ticking sound. Car is fine while idling, but when boost
is applied misfire and smoke appears. I need help,
does anyone have any solutions?

Did you code in the flow rate of your new injectors?

Yes i did

My only guess would be o2 sensors because that's the only thing you needed to take off related to that bank. unless you took more things off to give you more room. and it can be a pain to twist off sometimes and may get damaged. What color is the smoke? Looks kind of dark? I know there aren't any o2 sensor codes but you never know with these cars. Did you make sure the o2s were in the correct spots? Try going back to square 1 and swap your ignition coils around . Put 4-6 inside 1-3 and 1-3 inside 4-6 to see if codes change. Did you only change the spark plugs in the cylinders that were missfiring?

Yes i checked the o2s they are good and working the smoke is white but I'm coming to the conclusion that it might be the wiring for the coils or on top there

No i change everything to new spark plugs,coils and injectors

Something with the 02's. Did you use a gasket from the downpipe to turbo v band. what are your Afr's on that bank

[Occ224]

Can you attach a picture or 2 of what the wiring looks like

[jadams161]

Sounds like you did not wire something correctly. Mixed up oxygen sensors and/or plugs? Got a bad DME? What you replaced is plug and play so recheck your work.

If a engine malfunction light came up on your dash, a Shadow code should be stored at the least. Use INPA or Protool to read it.

It could be a number of things, but instead of guessing its better of you check and go from there.
