Question about 1992 Buick Riviera
Some bolt on the fuel rail, some are the fuel rail. Look at it. if it bolts on remove it and replace it. Sometimes you have to remove the throttle body to get it out. Be prepared to buy a gasket for the throttle body. The ones built in the fuel rail. Remove the 4 bolts and gently pry the fuel rail and injectors off . Try to clean the dirt and stuff off the engine by the injectors first, air works best. Most stuff will blow threw the engine, but a small bolt or nut will wreak havoc inside the engine. Being an old car, I would replace the injector O rings also. Lube them to get them back in easier. If you have a 4.3 in the car, disregard all the above. Remove the top plenum, and it just has a clip to remove.
