here's the situation. '92 rs 5.0 TBI: BLM 150's INT 140's o2 0.00 - 0.07. increased fuel pressure blocked off PCV because spring was broken inside it. drove around. BLM 120 - 140 INT 128 went as low as 117 02 still reading lean but better. the problem that i'm having is that at WOT it ran fine. at cruise lean. now at operating temp it sputters and spits. only at operating temp. until it gets there it's fine. the only thing i can think of before replacing the pump is that the relay is getting too hot and not sending correct voltage. will be replacing the relay shortly. just thought i would run it by you people before i get the pump replaced.

other replacement parts have been the IAC, TPS,o2, MAP, plugs, cap, rotor, fuel injector cleaning service. because listening to the guys at a tune-up place guessing.
