I’ve spent days looking on the forums for an answer to my issue.
Firstly my egr valve and throttle body were heavily gunked up.
Now cleaned, including the egr pipe and the boost/MAP sensor in the inlet manifold which was also totally crusted over.
Yes the inlet manifold is also crusted but I cannot do anything about this without major work.
What I am left with is rough idle.
I’ve hooked up my obd2 Creader and have no faults.
On live data what I am seeing is a fluctuation in the ‘egr percentage’, between 0% and 40% at idle. At the same time i can see the throttle body butterfly twitching in time with the engine hunting.
The egr pipe to the inlet manifold is also getting warm on idle even from a cold start.
I have no idea where the egr percentage reading is taken from or if this is even the issue
Any ideas folks?
