Running rich after taking on water
I underestimated a puddle and a splash of water got in the intake, it didn't hydro lock, it kept on running. But right after it had a terrible idle, poor fuel economy and cuts out for a second at 2000 rpm. It's a 99 4.0L
It had a code for the secondary O2 sensor (haven't replaced yet) so I don't know if it got another code yet but I will check when I can get access to a scanner.
I've taken out the distributor and cleaned it well because it got wet too.
What should I check next? MAP sensor? That's all I can think of

I boat my jeep all the time. Try WD40 in the distributor cap and just keep it running it should work itself out after awhile. I coat my distributor with a entire jar of vasoline then use some on the plastic breather elbow on my air intake and I tape the dipsticks in place and vasoline those to. It's kind of messy but I run my jeep till it starts floating all the time and have no problems other then gauge cluster going berserk. I have my intake ran through the firewall into the cabin and have my axle and tcase breathers plumbed into the intake.

Replaced MAP, TPS, put the scanner on it and I'm only getting a code for downstream 02 which has been broken for months, my problems only started after hitting the water

That'll still do it since it can't go into open or close loop(not sure what's what) it needs the o2 sensor to adjust fuel
