First thing to check are the little vacuum pipes. Prone to deterioration. Could be MAFs or lambda sensors. Since this is showing on the diags then it's almost certainly one of those 2. Hopefully for you it'll be the pipes or MAFs.

Don't forget to check the master cylinder vac pipe, too.

MAF sensors rarely show up as a fault code you need to log the data from them.
