I have a 2005 cobalt 2.2 base with a cold air intake that gives a p0171 code. Lately Ive been getting a p0106 code and Im wondering if its a related issue now that it is warmer outside. Could it be from installing a header that has a small exhaust leak?

Small exhaust leak could give you the lean code (P0171) but not the MAP code (P0106). That one is usually caused by a leak between "MAF" sensor and "MAP" sensor. Somewhere at one of the seams of your "CAI" most likely.

There are no leaks. Should I just replace the MAP sensor?

For the Map DTC, check your vacuum lines first before replacing any part. You do need Manifold Absolute Pressure in conjunction with a MAF as well. May just be a corroded hose.

My concern is the p0106 not p0171. P0171 will be fixed with a tune. As far as the p0106 there aren't any leaks so is it safe to say to just replace the MAP sensor?

You didn't find any leaks doesn't mean there isn't one. How did you check for leaks? Propane?
