1993 lexus gs 300 sputtering
1994 gs 300 115,000 miles, timing belt changed at 69,000 I've had it for 3 yrs and haven't had any trouble til now, it has started sputtering in idle, and especially during excelleration oh, and the check engine light is on. I've never had it tuned up have changed the serpentine belt though.

Possibly a misfire, I'd definitely check the codes to verify. Same thing was happening to me last week, no codes or CEL, but misfires at idle and under acceleration, as well as no acceleration past ~45mph. On Sunday, I found oil in the spark plug galley and it made it's way onto the plugs. I took out 1,2,5,6 (3 and 4 are covered by the throttle body, removal is a whole project in itself), and cleaned them as well as the boots. Everything is back in order now, hope this helps.

misfiring
what can also cause this issue is the brush in the distributor cap.....
i pulled mine the other day and realized that the brush had a piece broken out.
got a replacement and now its a world of differences
but as suggested before........
pull the codes from the computer........
do this by connecting E1 and Te1 on the DLC1 (in the engine bay) or DLC2 (under driver dash) and match codes in the link provided above.....
otherwise.... possible cause are as follows
air flow meter
spark plugs
distributor
