I was doing some wikipedia research and they recommend that I replace the map sensor, egr valve (doesn't stick, but may have weak springs), and oxygen sensor. I dont have any trouble codes, but these parts are at least 40,000 miles (about 3 years) old. Should I replace them?
By the way, I have replaced just about everything you could imagine except for these 3 parts, and vaccum lines don't leak.
have the same problem?
