Hi, I have a serious loss of performance after a EGR swap, throttle body clean and inlet manifold clean. I have changed MAP sensor for a spare one I have and also tried disconning the MAF air flow meter, no difference. My main worry is if the garage have dropped some of the carbon tar inside the inlet manifold. The car has about 20% power and shows the codes in the photo, even though the MAF has not been touched. The garage wont mess with it anymore, it when in with a EML on due to the low flow of air going in via the EGR valve. What can I check next ? I cant see how the MAF can get dirty from cleaning the Manifold ?
