fuel injector cleaner ?
I use name brand 93 octane gas in my 95 SC4, and have a new fuel filter. I have used Lucas fuel injector cleaner numerous times, but when I dont use it I get a little stumble at no load 1600 RPMs. I put a $ 5.00 bottle in and it runs like new. I also have new plugs and wires and no CEL.

i get the same exact problem.....as well i use the same injector cleaner as its reputable but not very often at all.
sometimes coming to a stop itll seem like its boggin out for a second every once in a great while not a big deal but it seems to be similar to your problem

fwiw, Far from the least expensive solution, but certianly the best. Remove the injectors, have them professionally cleaned, essentially rebuilt and reinstall them. This is far superior to fuel additive style cleaners.
The injectors are typically flow balanced to less than a 1% variance. When returned, the injectors look new, anything that can be replaced has been replaced, ei. filter baskets, o-rings, pintle caps. The injectors have been tested for leaks, spray pattern, flow rates and subjected to three ultrasonic cleanings and high pressure back-flush to remove particles.
Cost $18 each Witchhunter Performance, who I highly recommend. Worth a read: http://www.witchhunter.com/methods1.php4
There is a before and after photo there and it seriously represents what you can expect.
btw, Witchhunter suggests Techron twice a year for injector maintenance.
