burnout9

my old man has an au1 farilane, on cold start up u can hold throttle on 2000rpm and nothing happens,but about a minute into the warm up it hunts up and down , let it sit at idle the same thing hunting. also while driving it surges very slightly at all speeds until full throttle, then u dont notice it.

ive been told it could be temp sender, map sensor, or egr.
ive been searching the forums but all ive come up with is hutting problems with the eb-el series, im told these are different.

the car has had all the fillters done and recently it had the leads and plugs done beacuse it had a bad miss on load which is fixed now, its done 65,000kms.

any help would much appreciated

why will premium fix hunting?
A good start will be a vacuum leak. check all your hoses and fittings. very easy to knock one small hose off. have done it numerous times. the vacuum leak it has produced, is introducing air in to the intake that has not been calculated for by the air flow meter
