I just swapped the hoses and the problem is still there after it gets warmed up for 30 minutes.

It's the TPS. It's always read 12.5% at the closed position in the past and now it reads 15.5%. It might actually be the wiring which I soldered and heat shrunk back in March. There was one wire that I forgot to put the heat shrink on at first so it got wrapped in electrical tape.

Unplugging the TPS while the engine was one and plugging it back in made it stop idling high. The % reading was still over 15 but the ignition timing dropped from 15 degrees to 2, and slowly began to climb upwards. I viewed all this on my Actron OBD-II scanner.

I will say this about getting my leak detection pump vacuum problem sorted out (I might have mentioned that in another thread, I had tinkered with the hose routing years ago and had a vacuum leak from a bad connection I fixed this past week), I have more low speed torque and better partial to mid throttle acceleration, and my engine speeds on deceleration are a lot more graceful when returning to idle. My gas mileage has gone up, but that's to be expected since it was the metal gas tank line that was not properly sealed. I had noticed that it seemed like every time I turned it on the gas needle had moved, most notably after sitting for a night or a few days. I thought maybe it was just my mind playing tricks on me.
