Default Misfiring car need help

Okay so long story short i just bought a 1991 318i when i went to buy the car it had no battery so i installed a battery that was too tall and it shorted the battery terminals on the hood. I never drove the car before but now the car has a bad misfire in every load condition my question is could the battery short cause the dme to fry and there is my problem? Or could those misfires be something else ? Will these cars even start wity a bad dme?

Yes shorting a battery could have easily fried something electronically.

do you have a bentley manual, or a factory manual? you need something with some good detailed instruction on electrical tests.

No i don't will a car still be able to drive with a bad dme because i can still drive it to work. I notice the misfiring is worse when warmed up and the idle is kind of high.
