Low rough Idle problem??

[DOC23]

ok so intially i believed the low and rough idle on my redtop 180 was due to sum uprated cams (as i was told by previous owner) however from im led to believe there are just standard cams now

Now i am curious as to why she idles low and abit rough @ 800rpm
she drives spot on, boosts well and does not spike or creep.
when driving hard, there is a strong smell of oil from the exhaust.


what i want to knw is why she is idling low and rough and if its a more serious problem??

running a IC, 4branch with de-cat, t25, standard internals nd injectors

could it be the injectors?
the intake pipe which is kinked?
Worn rings?

also did a compression test and there is a constant 100 -110 psi across all cyclinders

did you try doing the compression test after putting a few drops of oil down the sparkplug hole first?

Either complete lack of compression or an air leak...pressure test your pipes and remove whatever D.V you have

did a compression test with and without a wee drop of oil got 8bar across all cyclinders
