Lexus IS 220diesel. 2008. stalls when warm on traffic lights but starts up fine and after a few pumping padel it runs great

[arnus106]

my car is driving me crazy. it starts out fine all the time hot or cold and runs like a dream and until (only sometimes not all the time) i stop on traffic lights it idles fine and i press aceclerator and it stalls but starts up striaght away and after 5 sec of pumping keeps going like nothing ever happened no hasitation either. just that light green and i want to drive off it just stalls and after pumping few times like 5 to 6 times it goes fine shoots up like a rocket ship and i also noticedits only doing about 23 miles to the gallon according to the onboard computer.

i have done..

EGR clean twice (just incase if i miss some dirty soot)

new MAF sensor

new AIR FILTER

oil change

Lambda sensor fully working

oxygen sensor reading sometime more then 1.2v ( cheap streetwise scanner )

lots of injector cleanner bottles in the diesel fuel (i buy fuel from asda)

im in the brink of thinking or breaking it for parts but its really a nice car in very good condition inside and outside and underbody is clean.

please help

looked through all the forums and can`t find any thing like my problem.

thanks

maybe do a full EGR delete as a last resort. 

otherwise I'd be interested in some interior bits if its black leather 🤣
