What sensor, if bad, will cause an erratic and high idle cold and hot and a major shift in the transmission shift points?

It might be a bad ground on the sensor in question, but I need to know which sensor it is.

Thanks to anyone brave enough to provide an answer.

Not that easy. Is it fuel injected or carb?

It is multi port fuel injected. It has a distributor. Timing is electronically controlled.

The problem is intermittent, I'm just trying to target the problem without attaking the entire electrical system with a multimeter.

Thanks for the response.
