EGR valve failure
Problem:
If the EGR (Exhaust Gas Re-circulation) valves fail, it can lead to a lack of power when accelerating. The EGR valve gets blocked up, causing poor performance and you may also see a blue/black smoke coming from the exhaust. It can also lead to poor engine idling.
Solution:
You can remove the EGR valve and clean it out to remove the carbon build up. You will need a small brush (tooth brush) and some carb cleaner to clean it out. This should fix the problem. Watch the video below to see how this is done:
