I have a low km (80k) 1ltr ute i need to get to idle smoothly for pit inspection, it was running well but has sat around a bit now doesnt want to idle at all and fluctuates up to 1000rpm when turned up.
Any ideas, its a maruti f10a

I know your switched on but I always start with the same process.

New fuel, old fuel causes all sorts of issues.
Carby cleaner down the throat.
Drain the bowl and clean the jets.
Fuel filter.

Have these been done?

And after that, check fuel pickup, lines and replace fuel pump.

Both my sierras had rough idles, caused by two of the above, one the fuel lines were crudded up and the other was as simple as changing the filter.

This may also help. Power to the idle solenoid and there's a filter screen somewhere allusive

[MrRocky]

Yeah couldnt locate filter screen anywhere gave it a good clean and blowout will see how that goes.



Was pretty filthy

Was about to say!!! Thats some ugly gunk in the poor thing

[MrRocky]

When fuel mixes with red clay dust its impossible to deal with.
Ebay china carb might have to do

[bumstein]

Of you've got time on your side, drop the whole carb in a jar of petrol.. Come back in a few weeks time and get into it

[MrRocky]

Ok after a blow out and a few other things i noticed the car temp sitting at half, changed seized thermostat now temps just under 1/4 and car is idling spot on ??? Quite odd not sure if related somehow

[bumstein]

Hmmmmm!!! No idea!! Take it as a win

Fuel boiling or getting too hot??? Only a wild guess.. Probably disregard that idea

[MrRocky]

I did think of this but stupid... ?
Or possibility ?

[bumstein]

Can't tell you through any actual knowledge sadly

Can only think of that or the valves aren't sealing 100% when it gets hot.. But then I'd expect it to run rubbish under load not just idle.. Speculation.. Sorry Mr Rocky, can't be more insightful here
