buick stalling Sign In

I have a 1995 buick lesabre custom, v6 fuel injected. Here's the ?, awhile back it started sputturing going up big hills, or giving it gas pulling away from a traffic light. Then would stall randomly, seems like it would only stall when i wasn't on the gas. It has a fairly rough idle, here's what i've replaced so far...

Fuel Filter
fuel pump
spark plugs
wires
checked ignition module, works fine
checked to make sure all were firing
correct gaps in plugs
ran fuel injector clearner through it
recent oil change
check engine light isnt on
no funny noises

i dont have access to a scanner, and i'm stumped. :(

Any help is very much appreciated, thanks for your time.

There are so many could be’s that without getting under the hood and checking things first hand, anything I suggest may take you on a wild goose chase?

If you mean you poured something into the tank that usually won’t help you if there is an actual plugged or dirty injector. Those cleaners are not aggressive enough to do much of anything; they have their place as a preventative maintenance item but not when there’s a dirt problem. Maybe try having the system professionally cleaned and then an injector balance test performed.
The injectors may not even be dirty but one mite be beginning to fail electrically?

Blush Check your cat. converter, sounds like it's plugged. Make sure you also check the muffler, somtimes the baffles will collapse inside and your car cant exhaust like it should, also, if that's a db1 system, you dont need a scanner to check for trouble codes, you can access the adl link with a "computer key" or a paper clip but if theres no codes or the light isnt on, then theres no need.

I'm having this exact same problem. The problem did semm to come back when my exhaust leak got a bit worse.....just trying to pinpoint exactly what I should do, and if I should take it somewhere or do it myself.
