Hello all eighty series guru's! I'm the proud owner of '94 eighty and have been grinding out getting everything dialed in. I'm at a point now where I'm not finding what I'm looking for and it is possible my lack of computer savvy is causing my issue. So if I'm trying to find help on something and it's already out there please point me to the correct thread. I'm going to post the thread I started in our club section for background if anyone wants to see what I've done so far:
https://forum.ih8mud.com/ca-jefferson-state-cruisers/708509-new-me-80-a.html
So now I'm looking to solve a few more issues and also looking for some direction on prioritizing them. My fuel millage is still suffering (getting about 8 mpg on the road), and I have what can best be described as a whine coming from the engine. As far as the whine is concerned I have replaced the alternator, removed the idler pulley, and I'm not running the AC belt (yet). I'm thinking that leaves the water pump, but I don't know that I've ever had a bearing whine from a water pump... I'm also getting coolant leakage from the "goose neck", from the top of water pump to the side of engine block. As far as other fluid leaks I don't have any leakage from the top half of the motor, but seem to be leaking from everything underneath...oil pan, front and rear (assuming main seals). Also have noticed a bit of a knock but not hammering so I'm thinking that will just be something to check out while I have the pan off. Okay now that I've rambled a bit I'll try to sum it up more concisely:
-TPS code 41 (and poor fuel milage) I can't find a thread or other info on trouble shooting and resolving this on an obd1 truck. My FSM and the threads I've found have the procedure but require readings from OBD2. If there is a thread please direct me, if not advice is welcome.
-Whine, assumed water pump?
-Minor coolant leak, pooling on top of water pump.
-Quiet knock, from bottom of motor that quiets after some time (~15 min.)
-Oil Leaks front rear and bottom.
-AC, no receiver or lines from driver side inner fender all the way to compressor.
-Straighten steering wheel, remove from steering shaft, adjust connecting rod, or pull wheel and put back on?
-Resolve exhaust leak and eventually get manifold to machine shop to have sheared studs drilled and tapped, and have buggered threads repaired.
Okay so I think that is pretty much my list in order of what I find to be a priority. AC is a little farther down the list than I'd like it to be, but I'm concerned I may have to disconnect lines to complete one of my other issues. Also as far as the AC is concerned I'm planning to have a local AC shop build custom lines, replace the "receiver" and charge the unit. If sticking with OEM is better than relocating the "receiver" and running custom lines lemme know.

). He is new to 80 series and trying to track down some of the issues. I'm at loss technically and suggest he started a build/help thread here in specific origin of the 80. We have some great talented (including him) guys in our club; but there is some odd stuff with the truck.
