1997 Chevrolet K1500 Cheyenne 5.7L MIL Lamp on
at idle and deceleration exhaust goes rich,long term fuel trim on both banks begins to decrease to [...] pressure stays consistent at 58 psi. we suspect a bad poppet valve hanging open on both cylinder banks,but are not sure the best way to perform an injector...
