I need help guys, I'm lost.
Car has been running rough at times for a few months. Recently it started misfiring and throwing random misfire and cyl 4 misfire codes. Last weekend I bought a new MAF and a new dp with cat. Both installed for a week now and problems came back. Its not misfiring now, but it is randomly cutting out.
I can't narrow it down to a shift point or anything. I've ran 2 tanks of gas and some sea foam thru it with no change. Have been getting awful mpgs as well.
Plugs and wires look good and only have about 20k on them.
Car currently has NO codes.
I'm at a loss for what to check next. I can take it somewhere for diagnosis but idk how to describe it and being a girl, they will think I'm crazy.
So any advice anyone has or things to check, I would greatly appreciate it.
