My Toyota Prerunner, 4 door, 94,000 miles, 4 cylinder had the check light come on 6 months ago and the code said that I needed to change my EGR valve. So I changed that valve but just over a month the light keep coming on than off a day or two later and it was still saying the code for the EGR valve. What could be the problem?
