1994 Clubwagon E-250 stalls when given gas but it will crank up fine.. and purr like a kitten until you try to give it gas.. I replaced the computer, the module, plugs, rotor,coolant temp sensor, oxygen sensor, map sensor, I cleaned the injectors.. and it is still stalling when you give it gas.. also while it's off if I leave the battery connected ..it will go dead in a few hours.. So what do you think is the problem???? I have been working on this van for 3 weeks now with no solution to my problem.... Help..help.. WHAT SHOULD I DO????
