Non scooby thread - car problem - help needed

[Marky-San]

Folks,

My little civic is idling at 2,000 revs and then starts 'hunting' between 1000 and 1800 rapidly.

Forgetting its not a subaru - does anyone know what could be the problem?  I know its a more general car problem.

Any help appreciated.

PS - tried 2 Honda forums and got 2 replies but nothing specific, hence my return to the techno-people

Is the honda motor drawing air from anywhere it shouldnt? Split pipe, gasket etc?

plugs or leads maybe????

Idle control valve needing cleaned?

not sure what the civic's engine is like, but most cars should use a MAF and Lambda sensors (later more for idling) just like the Scoob.

I get both check with a Honda dignostic tool. My Dad's Vectra was doing the same and narrowed it down to his MAF. I would start with the O2 sensor first though.

I'll go with the air flow meter.

Cheers guys,

I knew I could count on you.

I'll check the piping.  Get one of those diagnostic tools from Halfords and see what it says.

Might nip to my mums and pull the sensors of that car and try them - hopefully should mean I dont waste money on an unnessary sensor?
