Clean the Throttle Body. Disconnect the battery first! Check the vacuum system while there.
When done you will have reset the values that were stored, and the computer will "re-learn" your driving parameters. Takes about 100 miles to get the engine acting 100% right again!
I go down dirt roads (I know it's a Porsche, not a Jeep - but that is where the houses hide out) and have to clean my TB every OTHER MONTH! It exhibits symptoms like you described when it is in need of attention. It starts with a shaky idle, then sputters a little and degrades from there.
How was the airbox damaged by PO?
I installed a proper non-factory intake and am putting out much more HP. Is that what you mean? Some around here will swear by stock intakes…sounds like you have another problem going on.
Got a pic?
