The Clarets needed a late goal from substitute Thomas Hitchcock to rescue a point at home against Bath City.
Stringer’s side have now drawn three of their last four games but climbed to sixth after Hemel Hempstead Town’s defeat to Hungerford.
Chelmsford are still in good shape but Stringer admitted that changes may be necessary if they are to get back to their best.
"The way we ended is the way we should start and finish games, it's as simple as that,” Stringer told the club’s website.
“I know we've got players who are good enough to play in this division and win you games, but there's just too much inconsistency with desire or character.
“All the subs have worked well today so maybe I need to go back to the drawing board. Some of the boys may have had too long in the team and I need to move it about.
“I just want to see desire and lots of running and passion and I got that in the end and that's why we got a point. I think if we hadn't have changed it, we lose the game.”
