Engine barely runs when warm

[zavikan]

Car hasn’t gone even 1000 miles in the last 8 years, but has been periodically started and driven around town. Around 8 months ago I locked the keys in it and didn’t get around to getting back in until today.

Charged the battery and the car came to life no issues. As it warmed up it began to misfire and sputter. Barely made it home. No check engine light. Restarted the car a few hours later and same thing. Restarted next day and same issue.

Thoughts?
