Is there any chance of getting an update? I'm having the same problem right now with my wife's '07 4.0. I've cleaned the TB, replaced fuel & air filters, cleaned & even replaced the MAF sensor, and just replaced the TPS. It is still hesitating/stalling now & then which turns the wrench light and sometimes even the engine light (MAF code. Also got p016b once too) Any further suggestions or is it time to replace the TB?
