the ford tps, if thats malfunctioning can make it idle high, dont think wetting the electrics on these engines is a great idea, if all you've done is washed it, gonna have to say make sure theres no residue, run the engine hot to evaporate water, inlet malifolds are a fibre type and an old one wont respond well to washing, and the inlet manifold bolts can loosen off, so check there. Run it hot, check for residue in electrics, check manifold gasket, might be worth giving all engine loom connections a crc or similar water disperse, yeah. so I'd crc the loom connections first , then give the engine a water rinse, avoid the inlet manifold gasket, take it for a drive to heat and evaporate water, then go from there. Once its all hot and dry trying flipping it over to gas.
