ok here's an odd one for you guys... when starting the car from cold its a DOG. it'll ctch easy enough, but pop and bang its tits off (you'll need about 20% throttle just to get it to not stall and it'll pop pop bang bang (as if its mega lean or mega rich or something) after about 10 seconds it'll rev nicely and i can take my foot off the acceleratorand it'll idle nicely

any ideas? could it be the startup enrich table? ie its getting its value from this rather than the main map and after a while its swapping over the the main map?

its not as if anything really changes in those few seconds after starting so cant think what else it might be
