Suggestion

Also you could reset everything by disconnecting the negative battery lead for 30 minutes, reconnect and then do the re-calibration of the E-gas.

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

4 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 1 / ORIGINAL POSTEROriginal post

I think the PO may have used the wrong post cat sensor as both (post and pre cat) are Blue. Every pic I see has black/grey for the post cat. The question now is there a difference in the sensors and could there be any harm done? I have no codes and car runs strong. I do get an occasional stumble at idle, the tach drops and the voltages drops briefly.

POST 2Original post

The DME is very sensitive to the O2 sensors, so I would say you are good to go with no CEL codes. On the stumble, do you have a drive by wire (throttle cable) or E-gas? If the former, clean and check the ICV on the throttle body.

POST 4Original post

With E-gas, have you done a re-calibration? Turn ignition switch to ON (not start), wait 60 seconds, then turn to off. Should hear some whirring clicking sounds from the TB. Also you could reset everything by disconnecting the negative battery lead for 30 minutes, reconnect and then do the re-calibration of the E-gas. A drive will then start the re-adaptation cycle of the DME.

This is a source reference. Confirm exact model applicability in the original material.
