PCM Question

[Parkerbot]

Ok so my high idle issue has returned and I'm at a loss as to what it could be (http://www.automotiveforums.com/vbul...ight=high+idle). When I disconnect the battery and allow the PCM to reset the issue goes away. I get about 100miles or so before the issue will return...so the question I have is...when the PCM is reset are there any sensors that are ignored while it remaps fuel curves? If there are I'm sure one of them has got to be the culprit.

regarding the idle issue, check ect sensor and its connector

That was it...ECT connector was gummed up from a previous oil leak...cleaned it up and she's running great.
