so i have read many many threads about the EGR.. i read from someone that the egr is covered by a 150k warranty or something like that? some please explain.. i puled the codes from my car(CEL IS ON) and these came up..
someone already suggested that i clean out the EGR ports, that might be causing this code.... p0401-egr flow insufficient

And these other two codes i have no clue.. if anyone knows please help.. thanks
p0170- fuel trim malfunction bank 1
p0171- system too lean bank 1

 

Here is a great "how to" on cleaning your EGR ports.

I don't know about the othe codes though. How old is your fuel filter? It may be to clogged to allow enough fuel to flow for the engine to run correctly.

 

thanks for the input.. yea.. im ready to do the cleaning tomorrow.. but i had read that tehre was some warranty of some sort for these cars for 150k that if you tkae it to the dealer they clean it for free.. i jsut bought the car a week ago so i havent done much maintanance to it yet.. i plan on doing that good stuff hopefully tomorrow.. thanks again.. anyone else have any input on this.. greatly appreciated..
