2001 Mercury 90hp 4 stroke outboard motor

Engine idles fine, but when I try to put it in gear (forward or reverse) it stalls out. I noticed when I move the trim to 1/4 up, it will go into gear without stalling. I took it out that way and it runs low, but if I try to throttle down, it acts bogged but will kick in at full throttle. I can then put the trim to level and it is working the same way. Someone suggested it could be the throttle sensor, but wasn't for sure. I also noticed taking off and putting on the upper cowl, that I had knocked off one of the coil plugs for lead 3 and I cant get it back on tight. Could that be causing the issue?
