TPS electrical testing isn't always conclusive

The TPS test procedure in the WSM or Clark's isn't always conclusive.

Ever since getting my 944S 3-4 years ago it's suffered from a part-throttle hesitation - my TPS always tested to spec at the DME plug and at the switch itself(and it's always been properly adjusted) so I'd always discounted it as the source of the problem.

I finally decided what the heck, I"ll replace the TPS anyway.

Nice. The part-throttle hesitation is gone. What a huge difference. Took me a couple of minutes to adjust to driving without it!

Anyway, the old TPS wasn't operating entirely correctly despite testing good.

If you're suffering from a part-throttle hesitation, don't assume your TPS is good just because it tests good.
