Strange behavior but no code, should I worry?

Fuel Pump... It will start failing like this and not trigger alarms.

MAF is what you should look at first. I had the same issue. If you drive like grandma it would be ok the moment you stepped on it it would joke like someone was strangling its throat. Let go of the gas and all is well. In my case I have had a poor maf for a while. Cleaning could only do so much. Bought the maf from JD suggested vendor on eBay. All is well now. Yours may just need a good cleaning though.

Reread Jaber's statement, there is truth there you may have missed.
