My question is the same. DO you run vacuum to the solenoids after deletion or do you plug vacuum before solenoids? Do you leave harness plugged into solenoids? I think the air pump is for emissions, but it also adds air to the exhaust which prevents against backfiring and also wouldn't the ecm try to lean up the mix due the the reading of the o2 sensor reasing less air? I am having a similar problem in which my air pump seized up and has no belt on it (bought it like that) and now am dealing with vacuum heaven. Also, do you delete the egr to counteract the loss of air pump? I can just imagine, I will probably be getting 3 mpg when I get it running well.
Btw, truck is 1985 f150, supercab, long bed, 302 efi.
