Engine surges intermittently

a 2004 Mazda 3 ... surges strong at stops.
Occurs at random.
Does this mean a vaccuum leak or a dirty/malfunctioning sensor?

Might be your MAF, but that's just a guess. This could be a lot of different things. I would start easy and make sure you have a clean air filter and then look into possibly cleaning the MAF.

Can a 2.0L or 2.5L engine replace a 2.3L engine?
