Granada idle

[ilovegrannys]

I had the Granny out today, i stopped at a set of traffic lights in 'D' & the idle was flitting between 100 - 800 rpm! When i pulled off it felt as if the car was pulling it self along! When i pulled over & placed the car in P it was idling at 500 rpm. Any reasons for this? Does anyone think it maybe fuel related? Help please folks

Is it fuel injected ?

They are new plugs. My old man said the car was 'hunting', i have heard of this before.

Could be an air leak, check vacuum pipes for splits, inlet gaskets etc..

exactly right steve, those carbed colognes suffer from air leaks from the carb area

if you've had the air filter off recently or worked on the engine i'd go for an air leak, usually the small bore vacume hose go brittle and no longer seal/fall off
