Hi. Can anyone identify this part? It is for an 87 cavalier rs 2.0. Thanks.
Thatâs the throttle body with the fuel injector mounted on top.

Thank you so much. I thought of that but one fuel injector? I never thought that was possible.
Transitional from carburetor to throttle body to full injection system.
That technique was pretty common in the late 80âs, early 90âs, called âthrottle body injectionâ. Thereâs a mechanicâs joke about one of the versionâs name, âcross fire injectionâ, instead should be called âcease-fire injectionâ ⊠lol ⊠Throttle body injection is not used much these days. Modern cars use either âport injectionâ, where thereâs an injector for each cylinder, injecting into the intake area; or âdirect injectionâ, again an injector for each cylinder, but injecting into the combustion chamber.
That was a very common design in the mid-1980âs to mid-1990âs. The single-point fuel injection provides excellent performance and fuel economy compared to a carburetor, and cost a lot less to implement than multiport fuel injection. The Dodge Spirit/Plymouth Acclaim and Dodge Shadow/Plymouth Sundance were very common cars, which used this type of fuel system.
Our â95 Suburban had it, ran great throughout an Anchorage winter, way better than a carb.
