A long story short, I had the engine out and beside cleaning the injectors I replaced chain guides, chains, vanos... everything. I did not have this starting problem before.
Having said that it could be from anywhere... but the question is now how can I debug it.
The indy that I actually trust couldn't find the problem. I took it twice. I am thinking that my next step is to take it to the dealer but not right now.
I have the GT1,INPA what can I try/test/check to debug it?
