well i ran my car with the OBD2 and found out that it said my egr was going bad and my car would wanna bog out or even kill when im riding third gear at 25mph... i went to autozone and baught a new egr... ripped the old one off and put the new one on ONLY TO DRIVE IT AND HAVE THE ENGINE STILL WANTING TO KILL..... what could be the problem??? its really making me unhappy

what was the exact code or codes you were showing?

I wouldn't pay any attention to the Autozone guys advice for interpreting the trouble codes, just because you've got a code relating to an EGR part doesn't mean the part is bad. What are the exact codes you were getting?

probably got a p0401-lack of egr flow. Autozone doesn't sell the dpfe sensor required to fix it but they do sell the valves (which btw, never go bad anymore) so they sold you a egr valve that didn't fix it. Funny part is, the dpfe sensor is covered under a Ford extended coverage program for an additional 2yrs/24K miles on most 2002+ vehicles. It could also cause the stalling concern as well but it might need an iac valve as well.

Twist.... he has a 2000. Which is a DPFE car. hahaha. I know so many people who replace the EGR and then come to my dealership and complain the light is still on. I run codes and almost everytime they have the p0401.


P1400 - DPF EGR Sensor Circuit Low Voltage Detected
P1401 - DPF EGR Sensor Circuit High Voltage Detected
P0401 - EGR Flow Insufficient Detected
P0402 - EGR Flow Excessive Detected

All of these codes can be caused by this DPFE. It can cause stalling like Twist said. Its for 2000-2003( <--- some ) Mustangs. 4.6 /3.8 .

The focus is the worst, but have done Mustangs, F-150's... blah blah blah.
The DPFE, will cause the EGR to come on and off, or not come on or off. haha. And if you started stalling when pushing in the clutch, or at stop lights Check the IAC. You can remove this sensor and tap it on something solid and you will get droplets of water out of it.

BTW: Next time you have a check engine light on in youre 4.6..... go to the 4.6 section and check TSB's and REcalls first. save you time and im sure the 4.6 guys can answer youre questions better then in general tech section.
