Hi there new person.

I want to understand your logic:

Why did you change your MAF if you are having misfire issues?

How many miles are on your car?
What year is it?
Is it a manual or an automatic?
What country do you live in?
How long have you owned your car?
Has your car ever had the spark plugs, plug wires, or the ignition coils replaced?
Do you actually know anything about your car?
When was the last time you checked the oil level?

Why am I asking your for all this information?
Why didn't you provide all of this information in your post?

BC.
