My Buick misses and cuts back at about 45mph. When just idling it is fine. It starts to cut up when its warm and at about 45 mph. This car only has 62,000  actual miles. This is the first problem I have had with it. Any suggestions as to what it might be? Thanks Jimmy

Also had a same problem before. It's probably the ECM. Have it checked.

Food for thought!!! [I]

Has the fuel filter been changed? Restricted fuel flow not only shows up under demand of accelerating but also when the engine and fuel lines are hot, the fuel below optimum pressure, expands and does create vapor locks and other erratic fuel feed problems.

 

My aunt also fails to do some of her duties caused by her own Regal. Her Buick Regal Custom die when idling at red light? Is there any specific cause in this?
