i have a 2000l and i am getting codes for insuf.egr flow and both banks running lean.looking for some help.i have replaced the egr valve and the pdfe sensor and i am still getting the same codes. any help is appreciated thanx!

 

Some info on your truck would be helpful

Is it stock ?
If not list your mods
What was the last thing you changed ?
When did you change your fuel filter ?

mods are air force 1 air intake,granatelli mass air,acufab t/b and boost bypass.fuel filter has less than 5k on it.codes showed up before fuel filter was changed.

 

To take a wild *** guess at the lean codes it would be dur eto the Granatelli mass air - It is likely not calibrated to match your truck.

The Egr flow problem is likely something else - Try searching here for that - I bet there are 100 threads to pick from with the same issue...

Good Luck

Doug

 

thanx for the info doug,i will swap out the mass air this weekend and reset the comp.

 

i had the same codes with both banks being lean

turned out to be my maf sensor
it was out of range and causing my truck to run lean

 

Lean codes check your MAF it may be dirty. The EGR code is prolly a DPFE sensor. Hope this helps

took a look today and found the vacume line melted to the egr pickup tube.got new part ordered.will replace lines and reinstall oem mass air as soon as new lines come in.
