From IMDB's Knight Rider 2008 TV - Goofs page.

Anachronisms: As the thieves are going through the garage, a Tuned Port Injected engine is seen along with parts from the original K.I.T.T. Firebird. Tune Port Injection was not available in 1982.

Whereas bullet-proof, talking, effete, self-driving Firebirds were on every lot in 1982. Just not with tune port injection.
