88 bronco 302 5spd i pulled codes and got code 11 33 41 and 96 in that order. This has been sitting for about 5-6 years. Replaced clutch re did the battery cables plugs wires rotor and dist cap and it fired up without turning over once. I was impressed but i got these codes and it smokes like crazy and sometimes when you start it its got high idle other times its got low idle. But for sitting it runs great and has good trottle response.

 

Egr is not closing all the way, O2 not working right and elec circuit problem or relay with pumps.

 

How do i fix those. The pump seems to be runing fine. I had problems first starting it a yr ago with the pump relay being corroded and not letting the pump run but it works so why would that code come up.

 

Clean the egr and test the evp. Probe the sig-rtn and Vfer and it should be 5 volts. Resistance between the evp wire and the vfer wire should be about 5000 ohms. Apply vacuum to 10 in.hg and the ohms should go down to 100 smoothly. Test engine vac for ur high idle and o2. Ur o2 is probably reading it right because ur running lean. Measure fuel pressure and pull vac hose on fp regulator to see if it has or smells like gas. Test the circuit at the pump connection.
