i have a new to me 260e mercedes i picked up at an auction and it seems to be in good condition except when i step on gas the engine stumbles and then it smooths out (its like a bad accelerator pump in the carburator on the old carburated cars). does the 1988 260e have a cold start valve injector and if so could this be the problem. \

i also find the lights on the dash air condition and the dome light dont work bulbs are good and i don't find any fuses blown is there another place where fuses are?

any help would be appreciated thanks
