2002 Saturn SL1 Racing motor

So do have a sl1 4cyl u put v6 that would make it a vue or ls that yr with a v6.if it is a sl1 4cyl then I would put the air intake on start it up take some carb spray and spray around the gasket of throttle body and all those hard plastic lines on throttle body and don't forget rubber grouments that are under the lines look for a rpm change when spraying.most likely u have a vaccuum leak somewhere also check and make sure have everything plugged in wires etc.u can also check that hose the runs from ur valve cover to intake the short s shaped one.that's a good start for now let me know what u find.also donations and feedbacks are greatly appreachiated.
