Running issues after sitting

[BlckBox04]

So my car has been sitting a looong time (my fault I know)

I replaced the battery this morning, went to fire it up and after trying to crank it several times (return fuel system) the car is missing like crazy, down at least one cylinder, going lean and just sounds terrible. I’m going to replace plugs and coils

the whole situation is concerning to me as when I parked it the car was 100% fine and now it’s like a different car

Any guesses or insight as to what might be going on is appreciated

First guess bad fuel.

How long did it sit?

I’ve let mine sit 6 months on E and zero issues

Clean the injectors.
Fuel filter.
Good to get it out again!

You can try some injector cleaner for now but if it’s been sitting that long especially on C you’ll want to pull them and have them cleaned/flowed.
I’ve been there/done that, now I will clean them every season or every other.
