Running rough

Car started running rough between 1700 and 2500 rpm. No codes, everything looks good under the hood. Plug wires are fairly new and dont seem to be loose????

plugs were replaced when I put on long tubes about 1.5 yrs ago. Not sure about fuel filter. I'm going to spray the maf and check the vacuum lines.

PCV valve connection tube to the intake, is there any holes in it? Is the air-bridge set on the intake properly, especially on the bottom?

The air bridge came loose. I tightened it back up, but still have the problem.

Might pull the air bridge back off, extract the maf and spray it out with an electronic cleaner spray. Do not touch the element inside the maf. Just because the wires are fairly new doesn't mean one didn't go bad but before going there, need to look at other things, therefore not wasting money. How rough are we talking about? I mean, is it stumbling or just a slight miss? Does it happen while nailing the gas pedal to the floor or slowly accelerating?
