Default MAF Low Freq.. and O2's Slow response?

MAF Low Freq.. and O2's Slow response? I got those DTC's what does that mean? Bad MAF and O2's? I just replaced the O2's last month.. <img border="0" title="" alt="[Confused]" src="images/icons/confused.gif" />

What kind of headers do you have - any leaks? With the slip on collector dynatechs even with a good seal it seems that enough air gets through to buffer the gas stream and slow down the amount of swinging of the o2's.

The MAF low frequency is strange though - that's normally a problem. You might check the "Eng Sense" fuse under the hood to make sure it isn't blown. Do you get the code continuously or just once?

had the same problem with my car when I added a Slp MAF. I narrowed it down to two things, excess oil on my K&N, and a bad harness.
