my truck has been running bad and i've had two different readers read it and got two different answers one was something to do with egr pressure being off and the other was the MAF. What are some signs of a egr going bad.

P.S. i've already cleaned my MAF sensor and i've also seen a decrease in gas mileage.

Thanks

 

bad gas mileage for the egr and they are about $65 and takrs 5 min to install i would bet its the egr mine went bad the truck got really bad gas mileage like 8mpg then i got the code pulled

 

Ok about this egr... cus Iget about 9 or 10 mpg as well... what is it where can I find it and how do I replace it oh and code pulling? how does that work?

Thanks

 

replace both the egr and maf. Use stock egr. and switch to 10w30 motor oil. you should get anywhere from 18 to 22 mpgs.
