Howdy:
I have a '01 4.6 2wd with about 186k miles. Everything is running well except for this stumble/hesitation on hard acceleration. If I accelerate 'normally' no problem. Only apparently on WOT it hesitates hard then it goes. I have no check engine light on. Although recently I have replaced the PCV valve and the hose, air filter. No other under-the hood maintenace.
I did have the CEL for the leaking PCV hose, but again after replacing the hose and valve then clearing the code no CEL.
Any assistance will be appreciated.
Cheers,
Rich
