By the way - in cose folks have forgotten, some early models had improper instructions for setting the TPS.
You have to check this voltage between the Yellow and Black wire. Some early manuals have it as measuring between the Yellow and Blue which is wrong. To measure, you just push the probes in past the rubber seals on the TPS connector to touch the copper on the leads. It is most critical to get the closing voltage between 0.5 and 0.6 v.
