So I picked up a 1991 f150 5.0 automatic. Long story short. 93k miles. Barely ever driven. Super clean truck.
I did the usual. Plugs. Wires. Coil. Cap. Rotor. Air filter. Fuel filter. O2 sensor. And map sensor. Clean the throttle body and iac. And I replaced the entire exhaust.
truck runs great. But has a very slight miss at idle. And the cel will come on and off while driving. The only codes it throws are for the egr valve. I’ve replaced it with a known good one. And no real change.
someone convince me not to rip all this crap off and slap a 4bbl on it!
