Question
Car has been fine for 10 years now with little problems.  Beginning to have issues with running rough,hesitation, black smoke out the exhaust, mileage decrease etc... Ran check on computer codes and they are in order EO32 current/I039 current/I052 history/A011 current/R026 history.
I am trying to determine feasibility of repairing due to age.

Answer
E032 = Open MANIFOLD ABSOLUTE PRESSURE sensor.

I039 = COMPUTER COMMAND RIDE (CCR) Signal fault.

I052 = Battery was disconnected in the past.

A011 = Hi side temp circuit problem in AC/Heat controls.

R026 = Steering column voltage to low.


You need to CLEAR all the codes from the computer and see which ones return.

REPLACE the MAP sensor. Buy a new one so you can see what your looking for in the engine compartment. Make sure that the vacuum hose that is attached to the MAP sensor is NOT cracked or broken. Remove the hose from the MAP sensor and you should be able to blow thru it.
