Hey guys I have an 05 4.0 33K miles with a check engine light on. Had Auto Zone check codes and was told it's running rich and needs a Mass Air Flow Sensor?

They told me the same thing on my 99 and after spending 125.00 on the part had the same problem. So thought I'd ask around before just throwing a pert at my 05

Any one out there have any ideas?

Truck bogs down on light excel but if you put the pedal to the floor it's ok?

 

what are the codes? do you have an aftermarket intake on it?

 

Not sure of the codes numbers. Had the guys at Auto Zone read them. Had two codes, one for to rich and one for to lean. Truck has stock air filter. Tried to clean MAF but made no difference.


Also noticed the truck had a tear in the rubber air tube so I've already bought a new one of them and cleaned the TB.

Possible plugged injector/injectors?

 

How about clean the maf and tb again and reset the comp.
