why is my escape running lean


Asked by Jan 04, 2014 at 11:53 PM about the 2001 Ford Escape XLT 4WD

Question type: Maintenance & Repair

I had a po1136 code, running rough at idle and
stalling, checked intake for leaks, and vacuum
leaks as well, after repeating intake cat ran
better but now I'm getting po1131 & po1151
with a misfire in #5&6 cylinders and the front
catalytic converter gets red hot there are three
brand new cats on this vehicle with less than
20000kms on them

The misfires will make the cats glow as unburnt fuel is being dumped into them. Change out the coils on #5 and #6 and your spark plugs if they haven't been done. Clean your MAF for the P1151 with CRC MAF cleaner.

Maf was cleaned new air filter and all plugs new and new coils on 1,3,5 when the new cats were installed. The codes seem to change on a daily basis?


Maf was just cleaned before the cats got red, last week it was cylinder #1 misfire?

You're really going to need to hook it up to a diagnostic computer so the Fuel Trim and other monitors can be watched while the engine is running. Obviously, guess work hasn't fixed it yet.


Thanks for all the help and suggestions now all I have is random/multiple misfires but running better and not heating up the cats
