Do you guys think any fuel cleaner additives would help? I put a bottle of seafoam in a few weeks ago. Didn't really notice any difference

Default The wisest course is to start with plugs and boots

Of course blow out area before you start to pull cops ,then blow out each cyl before you pull plug . You certainly don't want that junk in cyl . If the plug well dirty it isn't going to heal itself . We always call for a hosp clean new plug job and new boots . Clean all cop terminals ,replace any connectors that don't lock on .Plugs are only good for 60k . Ford abandoned the 100k stuff .Torque all plugs in 25 to 28 foot pounds not by feel .No matter what boots and springs look like replace them .
You can damage pcm outputs if you don't address this problem .And that's a can of worms you don't want.
Start with this ,we have other tricks if this doesn't help .You really are wasting your time if you don't start here .This is your baseline .

If you have a broken arm and the pope pours holy oil on it do you think it will fix it ? Same with some of these liquid fixes on engines .

yeah I'm gonna make sure I get all the dirt and grime out of the wells. I'll definitely be tackling this problem this weekend. If cleaning and greasing the contacts and stuff doesn't work then will go from there!

I was just curious to if it would help at all. I know the seafoam doesn't do too much but still. I'm just looking for ways to keep the thing rolling so I can get to work and back reliably until the weekend
