Rpm jumps and one time it just cut off the rpm had gotten so low and when I’m at 30 to 40 it stalls a little bit

What is your question?

Drives roughly at times and is kind of loud

What makes this problem better or worse?

When I get my gas it seems like it’s trying to work right

How long has your 2009 Lincoln MKS had this problem?

It’s going on 2 to 3 months
