Noticed my car performs OK in low gear but bucks as I move up in RPM and gears (this started a couple weeks ago when I changed the antifreeze). I initially was thinking it was the transmission slipping but the more I drove it the more it felt like the engine was missing on an irregular basis. This symptom is making me lean toward a vacuum leak.
