Just wanted to put this out there to the experts-
I have a 2009 2.4 ti, which has remained standard until this week. Its on 50k and at 30k it had the works done to sort clogged up manifold, swirls and head etc. Ran sweet as there after, other than the odd typical alfa moments. Its been under alfa extended warranty until recently so have left alone for fear of invalidating warranty etc.
Long term I want to have the gus/njs/other treatment but due to insurance issues this will wait until renewal in next few weeks.
Anyway, to the point. Fitted diamond shaped egr valve blanking plate with the 9mm hole this week just to protect the inlet system etc. Now it takes at least two attempts to start when cold and there is clear hesitation at about 1500 rpm in any gear, not just the 5th/6th pulling issues that many have reported. Idle is lumpy and just appears to be running like a dog.
I have subsequently cleaned the MAP (pretty bad) so I assume the rest of the inlet system is the same again. The only thing is to do a ecu reset with battery off, which it is currently doing.
So to the experts; do you think the blanking plate would cause these issues? Or is it a bizarre coincidence. For info turbo spools up and holds boost fine and it does cane along when giving beans and there are no eml's. Dpf regens taking place regularly and always allowed to complete the process.
Im getting very embarrassed with trying to start the car for work each morning with the neighbours shouting the usual alfa jokes
at me so any advice appreciated.
Thanks in advance all.
