#3 of 8 both cats glowing by bernie17 May 16, 2009 (5:07 am)
hi i bought a 2001 escape, at the auction, it was running rough would not stay running and made a knocking sound, drained oil and found only 2 qts in pan, replaced engine, with like part, the part # on the valve cover and the calibration # match. i started up engine and let it run. at about 5 mins it started missing, little by little, cyl 1 went, and then 4, and then 6, and 5 intermitt comes and goes, there are no codes in pcm memory, koer test or koeo on demand. and the front cat or left side of engine turns glowing red and the back or right side of engine cat glows but not as bad as the front. i have switched out all the injs with the old engine and same thing, mas air flow meter, same even replaced the front cat, no change, the power balance is exactly the same every time, long fuel trim 1 is -1, and longfuel trim is -8, which coincides with the runs rough. it is pretty much doing the same thing as before i replaced the engine without the knock. so this is runnning way to rich or the fuel,is going right through without being burned and the cat are doing they're job. everything pretty much got replaced with the engine except air mass flow sensor switch with a brand new one and PCM which is the only thing i have not switched, i did reprogram however. no change. i have ruled out timing/engine due to it did this before enigne switch, any suggestions?

Replying to: bernie17 (May 16, 2009 5:07 am) I am no mechanic, but I would definately replace the PCM with a new or factory reman unit. You may have re-programmed it but it does not mean it is working properly. If you say that it is running to rich and you have replaced all the possible culprits then the only thing left that controls fuel mixture and what not is the PCM.   I bet you the PCM is doing all the fuss. JMO!
#5 of 8 02 pressure sensor valve burning up by inby5 Jun 03, 2009 (10:02 am)
I've replaced it once and I don't know what is causing it to burn up, but it burned up within five minutes after I ran it. Any suggestions as to what is causing it? Replies to this message: inby5 (Jun 11, 2009 6:03 am)
