"hesitation" F150 5.0L Auto
Hi there from Vancouver, BC
New to this site. Posting question for my brother who has a 1995, F150, 4WD, Auto, 131,000 km. Truck has been parked for a few months (?6) in the garage. Truck is inconsistently hesitating. Here's what happens: Driving in country and city, engine light goes on followed a few seconds later by a loss of acceleration even though still pressing on gas, then a few clunks (sounds like coming from front not far from our feet a few times and I think I heard a clunk in the mid to back range once, too) and then power is then restored and truck accelerates. This has happened at the beginning of acceleration (starting at a green light) and also just driving along without stops (country road 70-80 Km/h). This was still happening even after being on the road most of the day.
Any ideas anyone? Greatly appreciated and Thank you!
