Read evidence and context

Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

Discussions that contain suggestions: 1

0 original-poster resolution reports. Counts can overlap; they are not unique people or a success rate.

0 discussions have direct query context; 0 report a fix in that context. Other evidence may inherit the discussion’s subject.

Also, check exhaust system for leaks.

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.

POST 1 / ORIGINAL POSTEROriginal post

P1128 1-3 RICH THRESHOLD SHOULD I BE CONCERNED. I RESET IT AND IT CAME BACK 1 WEEK LATER. ANY ADVISE?

POST 2Original post

P1128 Oxygen Sensing Adaptation Area 2 (Cylinders 1 . 3) - Rich Threshold Fault conditions: Fuel/air mixture is so lean that sensing has reached its rich threshold. FauIt area: - Intake air system leaking. - Fuel pressure too low. - Volume supply of fuel pump too low. - Fuel injectors fouled. If DTC P1128 or P1130 (oxygen sensing at rich threshold) is stored in the memory, this means that the fuel/air mixture is too lean. Air leaks ahead of the oxygen sensors can lead to a fault in adaptation. Also, check exhaust system for leaks.

POST 3Original post

ALSO THIS COULD BE A BAD OR DIRTY MAF.IF YOU CAN READ THE ACTUAL VALUES ON THE CAR THE 4-6 CYLINDERS SHOULD BE READING OFF,BUT NOT FAR ENOUGH TO THROW A CODE.

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