CHiPs

From CHiPs Online:
At the drag strip, someone steals a bulldozer, but jumps off when the brakes fail. The bulldozer pulls out into traffic behind Grossie. Jon hops on it and crashes it into a building.

Back at the drag strip, a driver blows his engine. He and his buddies decide to steal the parts. At the strip again, we learn the CHP chipped in to get a car...except Grossie didn't contribute.

Meanwhile, the thieves start to get worried when they realize they took some CHP parts. Harlan tells everyone of their misfortune at the briefing. Their next time on the strip, the thieves blow a tire so they steal more.

After talking with a woman who had construction equipment stolen, Ponch spots the van that was used to escape by the thieves. He follows it.

The next day, the thieves are at the woman's construction site again. While Ponch and Jon attempt to catch them, one of them tries to escape in a forklift. He tries to kill Ponch with a forklift. (But he only "kills" Ponch's car!)

After Jon and Turner catch the guy, Grossie tells them he found their missing parts. Jon and Getraer chase two thieves while Ponch (in the "CHiPs" dragster) chases the thief in the other dragster. Ponch manages to stop him by opening his 'chute in front of the guy.
