B6 a4 1.8t misfire and check engine light flashing
Wassup guys i have a massive problem with my 1.8t. Ok so i have an all 4 cylinder misfire,turbo underboost, And a vaccum leak. Also a messed up cat. So i switched out the spark plugs and coils and it was still the same thing then i brought a MAF and it still running terrible. So i brought new injectors and a new diverter valve and i installed those yesterday and the car feels a bit better compared to how it was but it’s still misfiring pretty hard and I’m running out of solutions. What could this possibly be because it’s driving me nuts
