I guess I'm not really sure what you mean on all of that. By being hard on fuel do you mean its consuming lots of fuel? Also I think you need to, if you didn't, start with the distributor before you put a scanner on it. It really sounds like to me that the distributor was removed at some point and reinstalled incorrectly. There are excellent threads here to explain the procedures on pulling and resetting the distributor. If it runs I'm guessing you are only off a few degrees of timing or 180 degrees backwards. I'm not how much degree input these motors run at idle but I'm sure somebody has a thread here for it. I would definately concentrate on that distrubtor though. Use the search funtion here and let us know. Good luck.

I changed a bad thermostat today so now it runs where it should.
- disassembled and cleaned the maf and put it back in.
- put the hose back in from the valve cover to the air intake(it was missing).
- removed the distributor (gear looks worn)
- cleaned the pos battery terminal as it was caked with white and green stuff.
I am going to check the position of the rotor to tdc tomorrow. I also noticed a small pool of oil in the air intake right at the throttle body when I was cleaning out the maf, what's up with that?
So I went for a 15min drive and it warmed up to a line below the 100 mark and stayed there, so that's all good. It seem to run a lil bit better but still starts weird and am still getting the p1345 code.

Oil in the air intake almost always means a PCV valve is stuck open. However with your breather tube off this would cause an unballanced situation in the motor probably causing your PCV to stay open. I would replace the PCV just to be sure since they are so cheap and easy to do.

FInally got rid of the engine light. Went to the wreckers today and picked up another distributor with a much better looking gear than the one I had. I installed it the same way the old one was and got the code right back. It took me a while to find the right spot (4 times) . Starts right up, no bucking or anything. I also replaced the Pcv , it too was pretty munger up. Hope all of this helps with my etest. Should I Seafoam the engine to clean up the inside? it's coated with black stuff.
Thanks to everyone that helped me with my timing and other issues!

So I took the truck in to get e-tested today and it passed.
The test results were at 1865 rpm
Hc ppm limit 52 reading 16
Co% limit .29. Reading .02
NO ppm limit 578 reading 9
Dilution 14.8
Curb idle test results
Hc. Limit 150 reading 14
Co% limit .70 reading .05
NO limit N/A
Dilution 13.8
It took a little bit of work to achieve. The thermostat replaced (old one was
stuck open), vent tube installed(was missing), reset the distributor (was one
tooth advanced), cleaned maf, replaced Pcv, a heavy metal catalytic convertor, cleaned battery terminals (were heavily corroded ), and a bottle of CRC Gaurenteed to Pass.
Now I can work on other more interesting things on the truck.
