96 4.9 help with codes
I have posted on other threads,thought id try this one too.
Truck runs like crap,seems to idle ok ,but sometimes misses and sputters when i give it throttle,and other times its ok.When i put it to the floor,while driving,it bogs down,like it isnt getting enough fuel.If i park it for a bit and restart,sometimes it misses and sputters at idle and cant get any revs at all.When this happens,i give it some gas,i get a popping noise in the air filter tube.I can let it sit for awhile and maybe it`ll run ok ,and some times it doesn`t.
Keep getting codes 171,174,1401(pending)and 1409(pending)
I`m thinking i need a new DPFE or EGR vacuum regulator sensor.
Also wondering if the pre filter on the fuel pump might be dirty enough to restrict fuel pressure and set off these codes
Sure could use some help,truck is in great shape and only 130000 km,but i cant trust it on the highway this way.

Well,i got rid of the 1401 and 1409 codes by cleaning the filter on top of the vacuum regulator solenoid.Sure made a difference so far.I`m still getting the 171 and 174 codes tho,i cant seem to find any vacuum leaks,cleaned the MAF.So i think it might be the filter on the fuel pump being dirty.Can you buy just the filter?
