lots o codes

173, 176, 177, 327, 332, 542, 543

173 = system rich on RH bank
176 = system lean on LH bank
177 = system rich on LH bank
327 = DPFE output below minimum
332 = EGR valve opening not detected
542, 543 = fuel pump secondary circuit failure

The 02 sensor related codes tell me that either you have bad 02 sensors or you have injector issues. I would replace the 02 sensors and reset the codes

The DPFE and EGR codes suggest that the passages in the EGR tube are clogged and/or that the DPFE sensor is unplugged or bad.

The fuel pump codes are set when at some point the engine stalled, and can be ignored.

Yeah that 327: I'd take the dpfe off and see if the tubes are clogged, I took my off and found the problem right away, and I just replaced the egr with a new one just to besure!

I agreed rudydist on the other things

 

[mattsho1993]

well, my rear O2 sensor was unplugged plugged that in the fuel pump one i had corrosion on the ground and fixed that ill reset tomorrow and let you know the rest as far as EGR where did you get your new from...??? ill also if it will help pull EGR off and clean all with carb cleaner... Let me know....

 

[rubydist]

typically, its not the egr itself that is the problem - it is the small tubes that run from the egr so the pcm can sense if the egr is working - those small tubes need cleaned.

 

[mattsho1993]

can i take egr off and spray in through the hole where the gasket sits flush with intake....

 

[rubydist]

no, its not the main pipe from the exhaust manifold to the egr valve, its those 2 little tubes that come off the side of that pipe that typically get clogged up.

pics??? the little metal kinda S pipes?

ok i also am getting poor mileage... I ran out today pushed it to the station put $5 in of 89 i got 1.586 gallons ran it till it ran out again i got 20 miles... i did it to see my milage... my main driving was 10 miles from gas station to house to town at 60mph then i drove through town at 35 stopped at my girls... then went home... a total of 20 miles i figured it to be about 13.3333333333 miles per gallon this is bad? Yes???

There are other ways to check your gas mileage than letting your car run out of gas.

Did you replace your O2 sensors yet? I don't think the EGR codes will cause bad gas mileage but bad 02 sensors will.

 

[mattsho1993]

not with new ones but with ones that i didn't have problems with prior to replacing them?? thats my suspect... anyway to test them?
