What is this supposed to do / Partial throttle misfire diag.

[StarquestMan]

Part number is MD612803 if you need one. I don't think any aftermarket ones are available unless I'm wrong. I couldn't find any at any parts store when I looked.

A DIY on how to do it without any factory level tools that is.

All you need is an ohm meter to check the TPS and you can do it with the carb on the engine. The manual in the FBC System section describes what to do and the resistance measurements you should get. Besides minimum values you want the ohms to increase gradually and evenly as the throttle is opened and closed through its entire range. Dead spots or erratic changes in measurements are signs of a bad TPS.

Yeah, I know. I was just wondering if it's a common enough problem that it would be worth assembling all the info in one place for people without the resources or knowledge to figure out how to test it. If it is, I'll take some pics when I do it and throw one together.
