The car runs great overall and cruises at 70 just fine. It rides on a set of Michelins and feels quite smooth. The issues are pinging on even light acceleration and a rough idle. The code 32 confirms it as EGR related so that makes sense. I ordered a repair manual so that should help. In the mean time, is the EGR valve controlled by the computer and a solenoid, or just by vacuum? I'll removing and cleaning out the carbon but sure how actually works
