Chances are the MAF is the problem. However, I need the actual code number to be sure.

If you can, send me the code.

You kow, after I hit submit today, I started thinking of what you said, " incorrect baromaetric pressure, " and got mad at myself. That is the job of the MAP sensor (manifold absolute pressure) sensor. I'm sorry about that. However, if you didn't find out, the code would have told me. On the other hand, the mass air flow sensor (MAF) does a similar thing. It identifies the pressure / volume of air pressure entering the intake. Regardless, that is what happens without a code.

Thanks for using 2carpros. Com and let us know if you have questions in the future. I promise to nail it for you next time.
