cm870 engine light and running rough

[Signature620]

Does it run for a couple of seconds after key off?

Did they clean the disc and plates behind the shutoff solenoid or just change the solenoid?

Check to make sure the shutoff solenoid wire is tight and not rubbed on anything.

Make sure the locking tabs are all the way installed on all four fuel actuator connectors - These can be hard to install because fuel makes the seals swell. When one of those connectors is only halfway in, you can have rough running or misfires without fault codes.

Could also be a coincidence and we'll have to wait and see what the fault codes are.
