I have a 1998 chev. Blazer that is hesitating during aceleration. The service engine light has came on and I am getting a p0405, and a p0300 code from a scan tool. When I researched the codes they said that the ecm has detected the EGR position sensor voltage was too low. I cant seem to find any part matching this desciption for my vehicle.I dont want to buy unececary parts. Please heip with any advice on what I should do next.

You have an EGR valve-could be causing the P0300 Random Misfires
