Loose plug wire could cause a misfire, but I would work one problem at a time. Keeps you from chasing your tail. I have people who will say "Well I changed the coils, plugs, ECM, crankshaft sensor and a cam sensor and I still have this problem" With the quality of parts these days it's unfortunately rather common to have a bad new part. In the shop I tend to test a lot more so that when I say "This part is bad" I'm 99.9% sure it's bad. However, on here that's a bit hard to do as most folks don't have scan tools and scopes at home. So, I can't say "Well hook a scope to this point and send me the waveform" Or "Use the scan tool to disable the coil on that cylinder to see if it's the problem" However I would take a look at the wire and see if it snaps into place or if there is another problem.
For the pressure sender, they can be a bear on some cars. At least your engine isn't like somewhere they put the parts inside the engine like GM and Ford. It's so much fun when you have to take the engine half apart to change the spark plugs or starter.
