+18 1997 Silverado 5.7L Idles Too Low No Check Engine Light References. Web ok on the way the my 1997 f150 4.6 l 180,000 check engine light started flashing and running rough and then the light went off, also we took the aftermarket. There has been no check engine light except when key on, engine off.
Your silverado has two air. Restricted air injection check valve. Whereas a steady check engine light may mean you merely.
