My 2005 Buick Lesabre runs good & then the engine boggs down like it wants to die and then all of a sudden it surges forward fast and then drives good again until it starts to surge again. Earlier it would start surging when I came to a stop sign but now it starts surging while I'm driving. I've had it in & out of the shop since Nov. & they still can't figure it out. I have Multiple Sclerosis and I really need my vehicle to get around. I would more than greatly appreciate any info you could give me! Thank you so much for your time!

I've had this problem before on that engine and it turned out to be a bad Mass Air Flow sensor.
