2004 Chrysler Concorde Q&A
2004 Chrysler Concorde Question: What would cause the engine to "buck" when during sudden acceleration?
When passing or attempting to accelerate quickly the entire car "bucks", it's not a stutter or hesitation but rather it feels like the car is going to stop dead in its tracks. It only lasts a split second then resumes normal operation. I have recently had cam and crank sensors replaced with OE parts, water pump, timing belt and coil packs have also been replaced. The only other issue is that the car will stall frequently on start up or when in heavy traffic. - bham311
Any chance wiggling the key in the ignition switch aggravates the symptom? When it stalls , does it start right back up? When it 'bucks' on you out on the highway , do the guage lights all flicker? - ziptie12
