Van running rough help please

Question type: Maintenance & Repair

I recently purchased a used van ( dodge
grand caravan sport '03) everything was
alright bringing it home except the
speedometer wasn't reading till it hit 100.
Than nearly home it started misfiring. Hubby
changed the spark plugs. It was running fine
idle fine but the engine light came on right
after they were changed. Said code p0300
and p1684. It bow started to idle rough
again and when you come to a stop it
spudders as if its going to stall. Give it gas
and it doesn't accelerate until it hits redline.
It's very hesitant. Hubby thinks coil pack but
I'm not 100% certain it is. Anyone know what
this problem might sound like?

I would also like to point out that there is an awful smell. At first was like ashfault.. Now its just like burning rubber or plastic. That's smell only seems to come while trying to accelerate
