Will 2.2l engine from a 99 cavalier fit a94 sonoma?

No, a 2.2L engine from a 1999 Chevrolet Cavalier will not directly fit a 1994 Chevrolet Sonoma. While both are GM vehicles, the engine mounts, transmission compatibility, and other mounting points are different enough to make it a very difficult, if not impossible, swap without significant fabrication and modification. The Sonoma likely used a different generation of the 2.2L or a completely different engine altogether.
