No SES light I assume. I looked through a bunch of TSB's. I found on stating you could have a faulty MAF...not faulty enough to set a light, but enough that it's starting to show signs it's dying by possibly sending a low signal back to the PCM.
No ses light but I'll check later for pending codes... I did forget to mention that sometimes under load I can have a slightly jumpy rpm, especially around like 2-2.5k rpm up hill. I can feel it jumping and see it on the tach
