3.8 #1 misfire on my grand caravan

Ok so a bit of an update.
I went and bout the i take manifold gasket kit. Came with upper Mani rubber rings also.
Pulled it all apart and cleaned it a lightly sanded it all. Noticed some pitting where ports were matched to flat connection surface from Mani to heads. Didn't look too bad. But still worries me. I should have e taken pics.
I put it all back together. then when I started it I noticed it was leaking coolant between head and manifold. I had a party to get to so I said screw it I'm driving anyways. Then I drove the 45 minutes to the party got out and looked under the hood and it stopped leaking. Cool t res is still full. I'm gonna a check the radiator level tomorrow. It will be odd if it just stopped leaking. Especially since I didnt go and tighten again as I didn't have time.
Anyways when I popped the hood to change it I noticed my battery was boiling water out the caps. Ya me. Blew a cell. Good thing I buy duralast gold from auto zone. Wasn't in the 3 yr warranty but was prorated and I paid 108 for a new one. I always buy bigger batteries than the vehicle needs cause I run nice stereos. My van for instance has a 2000watt system.
So I slap the new battery in which resets my computer. Drove an hour and half home and engine light is still off. And get this my interior lights start working again well not the two up front which may just be blown. Odd that a bad battery would let my 2 rear lights work but not the middle sets of lights.
Felt alot easier pulling up hill accelerating.
Still has a shaking sputtering almost feel when idling. But I do know my alternator is going bad. The pulley is on tight but wobbles. So ya next on list.
I do think the miss is still there but seeing the coolant leak it doesn't surprise me. I did have the missus rev it up multiple times while I was behind it and it wasn't leaking fluids out the exaust pipe which is good news. Could barely see the exhaust gases coming out.
On another note I put new tires on it from big o and had them align it as I upgraded the struts and shock a couple weeks earlier that have the ability to adjust the alignment where my old one couldn't. Well I noticed my tires are bald after only a few thousand miles of driving. And it began shaking. The only thing I haven't replaced in the front end are the CV joints. So I replaced em. The whole front end is about a year old or newer. Rack and pinion, tie rods, shocks, ball joints etc.
So I noticed they stripped my week stud bolt for the struts on one side and the bottom nut and bolt we're hand tight on the driver side, face palm. The top one did t get torques barely more than hand tight.
So I took it to a different big o I trust a lil bit more. Sat they are gonna give it a shake down and try and find what's causing it. Tires are under warranty and will get replaced. They may try and prorate them. I have a feeling if it's the vans fault and not theirs I may be replacing the rack and pinion again. Good thing it's under warranty too. Just sucks cause it's a pain in the *** to do. I think shop rates at 8 hours. I can probably do it in six. But it's a pain lol.
I hope everyone else is having better luck than me haha
