Sputtering when I accelerate
Not enough information, add more and we will try and help
Is all maintenance up to date? Has anyone measured the fuel pressure yet?
What codes, if any, are stored? A misfire would usually turn on the CEL and a code would be stored.
If it has a distributor, lateral play in the shaft due to a worn bushing could do this. A fuel delivery problem, too. Corrosion and/or wear of the distributor cap’s posts and/or the rotor, too.
