2004 Ford Freestar 3.9 liter with 130,000 miles on it. After many failed attempts I simply cannot get this van to run right. Currently reading P2196 and P2198 O2 codes, even though I replaced them yesterday. Codes cleared right after installing all four new O2 sensors, but came back within 10 minutes of driving. I also had just replaced the EGR valve (less than 50 miles ago) as it was throwing codes as well (but not since I replaced it). Found a missing bushing on the front bank intake runner co

I have a 1997 chevy lumina. i had 2 coded before, po420 and po401. i changed the egr valve, and now the po420 is gone. i just replaced the egr tube, cleared the codes, and now the po401 is back. car sounds better, but i wanna get the code and service engine line off. any ideas?
Well, the po401 is saying is that the egr valve has restricted flow. After changing the egr and the tube, something else is causing the restriction. a more thorough diagnosis is recommended. The po420 code sounds like a possible catalyst failure or a ... 1997 Chevrolet Lumina

It may be the vapor canister. It is filled with charcoal and the vapors from the fuel system are sucked through it. If the diaphragm in it ruptures, you will get charcoal powder sucked into the egr system. You can clear it out and it will just **** s ... 1997 Chevrolet Lumina

I am at my wits end with this check engine po401 exhaust-gas recirculation and differential pressure. I have replaced the EGR valve and within a couple of miles it came back on. I have a OB2 reader and cleared it but failed the smog test in Ca because it didnt drive through a full cycle. I went to my mechanic and he suggested I replace the EGR selonoid which I did and then cleared the code. Again it came back on. I then read that the culprit could be the DPFE sensor that is part of the EGR famil

#$%@ P0401 code problem- 3.2 SOHC Trooper. "Insufficient airflow"- I have done it all from replacing the EGR valve to cleaning the pipe, hoses, throttle body, channel from the EGR valve to the intake manifold and everything else I have read to do or says to do in my manual.

I replaced the EGR Value because the error code indicated and said EGR Value insufficient flow. The engine light went off for about a week and came back on. I replaced the EGR valve with another new one thinking the first one was defective but the engine light did not go out. I noticed that when I increase a vehicle's engine speed by pressing down on the gas pedal or advancing the throttle while the vehicle is stationary it misfires. Please advise.
