ok so a few months ago my check engine light came on, paper clipped it and pulled a code 25 and 32, egr valve and a faulty air temp sensor, I replaced both sensors and this fixxed the problem. now its pulling the same exact codes again. does anyone have any idea why my egr valve would go out so quick and why does it cause the air temp sensor to jack up. also I have a rough idle and hesitation in acceleration, effects of the bad egr valve? thanks in advance for the help

 

Why did you replace the egr and sensor? When you took off the old egr, did you clean all the crud out of the hole where it bolts on? Im sure the new one is just jammed up... Could have just cleaned the old one.

 

yeah, I replaced it before I became aware that they could be cleaned, next time ill do alittle more research, but my main question about this is why would both sensore trip and the same time? crossed wire possibly? or are they some how connected?
