Diagnostic guidance. Suggested checks and possible repairs are separate from the owner's reported results.
Ask for an itemized description and the maintenance-schedule requirement or diagnostic finding supporting the service before deciding.
Guidance references and applicability
Source: This question and its visible discussion. The roadmap distinguishes the original owner's reports from other participants' experiences; proposed follow-up is editorial guidance, not a confirmed diagnosis.
Thanks for the input, still haven't decided, it seems a lot of $ when they told me they just clean the fuel injectors.
Discussion summary
What is an emission service?
The owner of a 1994 Civic with 140,000 km asked about a dealer-recommended emission service priced at $159.95. The owner later understood the proposed work to be fuel-injector cleaning and reported no current running problem.
Reported outcome: No service or resulting improvement was reported.
The quoted price is historical. The discussion does not establish that this cleaning was scheduled or necessary for the vehicle.
