So as many of you know from reading my threads ive been dealing with several issues.Well i went to PEP BOYS today and finally got a somewhat bearing on my SERVICE ENGINE LIGHT.The service guy was able to pull up code P0336(this one was kinda expected as id had other people up here suggest my crank sensor was going bad.)The other 2 codes were P0401,P0441.Tech said both were EGR related P0401 READING WAS EGR FLOW INSUFFICIENT,and he said the other was saying i needed to get a further diagnostic but still EGR related.He said there was a 4th code pending but had to do the diagnostic to determine($90 for the diagnostic).I do need someone to explain some of this EGR thing to me and whats required to fix it. So then i had the guy write up an estimate,the short of it is for parts and labor on EGR valve and knock sensor(cam sensor) plus their diagnostic(they call this their drivability evaluation) id be looking at a total of $583.23/labor was $305.99 and parts $198.18,other $67.40 and tax $11.66.Im not planning on paying these guys that considering i can get the parts for way less and have already had local mechanic tell me he would do the cam sensor for $25.One thing i would like to know is whether there is any computer reprogram or relearn needed or is it just straight replace and go?
