check for vacumm leaks warm up engine poor water on intake gaskets and injector seals if engine stalls or runs worse its sucking in the water thers your leak.
if not clean throttle plates and IAC motor
SOURCE: engine hunting
If the car is a fuel injected model there are three possible answers.
1/. If the oil is very old it may be affecting the gasses in the exhaust thus causing the Lambda sensor to give incorrect information to the computor-change the engine oil.
2/. Check that the throttle body is clean inside, any tar residue in the body or bypass port can cause hunting.
3/. The coolant temperature sensor may be faulty and giving an incorrect signal to the computor.

notorious for being very hard to time both carbs ..sim. probs.haunt many multi carb . set ups just ask any one with old triumphs .if carbs have never been rebuilt i think it might be time .if they have it might be time to replace .if replacing try finding ones with a fule management system.
SOURCE: Revs ''hunt'' on tickover, sometimes revs drop so low car cuts out
Thanks to some advice I have fixed the problem with my Granada. The pipe work from the exhaust manifold to the inlet manifold has a short piece of plastic pipe which needed replacing. This seems to have done the trick.
I would like to thank you for running this site. Without it I would still be re-starting my car each time I stop at a red light!
SOURCE: fuel pump causing engine revs to "hunt"
these were the best engine ever built by Toyoya they always had a tendancy to do this ,make sure all the vacuum lines are connected nand the idle should be set at 800 rpm. you seem to have to give them a bit of revs to over come the problem
