Okay, I've got a 1990 F-250 2wd. It has the 302/E4OD combo...lately it has been acting up. My issue started out as a small jitter at low throttle which occured mostly at highway speeds (no CEL) to a the situation now, where it feels like it is misfiring constantly whether I'm giving it gas or idling and has a hard time getting up to speed. I checked the codes-

KOEO codes:
11--System OK
32--Running; Continuous memory: (Trucks ONLY): EGR pressure feedback fault (1985-89 models)
41--Running HEGO (HO2S) sensor voltage low / system lean
41--Continuous memory: No HO2S switching detected
95--ENGINE OFF, Continuous memory: Fuel pump secondary circut fault

Things I've replaced recently-
Ignition Coil, New Spark Plugs & Wires, Distributor Cap+Rotor, MLPS Sensor, O2 Sensor, PCV Valve, Air Filter

I've made sure the spark plug wires were installed correctly, I'm pretty sure they are NOT crossfiring.

The misfire seems to get worse as the truck warms up...

any ideas?
