# Service bulletin A22010A

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

## NHTSA's summary

ServiceNews Article \- When diagnosing a Fit within the above VIN range with a misfire complaint, start by doing service bulletin 21\-007 \(Carbon Buildup with Misfire DTCs\) instead of replacing fuel injectors. These vehicles use an improved injector design that addresses the failures that may have occurred in previous model years. In fact, fuel injectors within the above VIN range with misfire complaints were collected and found to have no defects that required part replacement. Replacing those injectors may have reduced the number of misfires temporarily, but most likely didn't address the actual cause of the misfire. The recommended repair for these vehicles is to do the intake valve cleaning procedure described in service bulletin 21\-007 \(Carbon Buildup with Misfire DTCs\).
