Hello. I have the car listed above with 16v with petrol engine. I bought it in October, and I had a check engine light. Went to service, it gave me P0402, EGR excessive flow and P0302 cylinder two misfire. I changed the spark plugs obviously when I bought the car, ignition coil in December and EGR valve one week ago, both new ones, and two days ago the check engine light was back. I put it on a tester, and same trouble codes. Also I got a rough idle (600 rpm), sometimes it drops even to 400 rpm when the engine is already warm, and saves from cutting off, pushing up to 1000-1200 for a second. There are no other trouble codes, besides once I got P0171 System too lean, but when it got removed it, never reappeared. What could be the problem? (On the right bottom corner you can see the dates, when the trouble codes occurred. One is with the sensor code as well, that is when we tried how the car works without EGR valve on).
have the same problem?
