Re: buick is sluggish
Welcome to AF.
What do you mean by sluggish at 35 - 40? Is that under light, moderate or heavy acceleration, cruising? What is your current mileage. How old are the spark plugs and ignition wires?

Re: buick is sluggish
It is the best starting point since secondary ignition issues can cause a similar issue. The other possibility is the autotransaxle torque converter TCC lock/ unlock function which could cause the fishbite/chuggle effect.
Best way to tell how old the spark plugs and ignition wires are is to look at the identification markings on the plugs and wires. For wires if you see the GM Packard markings and the cylinder numbers on the wires then they are the original (OE). The OE plugs from the factory were the AC Delco 41-921 double platinum.

Re: buick is sluggish
I don' think anyone is suggesting you replace the torque converter, that is a major job! If you do the wires & plugs and that does not restore power, suspect a clogged catalytic converter. BTW, do you have any DTC's/CEL's (Diagnostic Trouble Codes)?
