Yes, it could, now go see if it's the relay or a connection before you drop any coin on a new maf.

What year is your car? The relays are on the driver side (by the brake booster). When mine threw a code 34, it ran horrible and puked black smoke out.

The MAP signal is too low at a given throttle position and engine RPM. All you need to do is find out why. Start with the simple things, like vacuum leaks. Check hoses, gasket surfaces, the PCV system, power brake booster, and EGR system. You might also want to verify that the MAP is sealed to the intake, and that the electrical connector is clean and well conected. Then you can measure the MAP signal at a given vacuum to make sure it is reporting correctly:

And people always send me hate mail for asking questions before actually posting answers! This thread will be exhibit A.

How about you fill us all in on the rest of the story (I'm listening to radio too damn much) as it'll probably help get you a relevant answer.
