Just clean out erg system,unless you don't have one on car.I have an extra one for sale.
well i just had the hear port and polished, 3 angle valve job, new valve stem seals. I cleaned that tube that goes from the back of the engine to where the intake manifold. I also cleaned (maybe not as good as i should of) the whole intake manifold and that thing that says EFI + the EGR system too.
I even posted pics about my engine and head
It seems that the outside of the engine is cleaner that than the inside :roll:
