A TPS is a pot, but and Ohm meter does not always show a problem. Found that out working with a TBI Omni. The TPS can get noisy like an old radio volume control. The increasing change in TPS value, triggers acceleration fuel adders. Noise does same thing.

How can a new TPS go bad? Silicone lubricants are evil around pots and contacts.

I would't blame solvents on a TPS failure as most of them are sealed up pretty good. It is a mechanical device, it can fail from wear. I serioulsy doubt this car has been driven enough to wear it out, but it is an easy thing to check off the list as being good. Checking with a ohmmeter should be fine, just sweep it very slowly.
Signals that have an AC or DC switching frequency like crank and cam sensors, coil signals, etc are the ones that create electrical noise. I would assume since this was a pre-packaged deal, the harness came with the appropriate shielded wires for those signals. With that said I wouldn't recommend running ignition wires near the EFI signal wires just to be extra cautious.
