Ok guys trying like mad to get this car to daily driver status but having a few problems so I wil post up whats its doign and see where I should go next and what I should try

The car 1995 jag XJR 102k

I have a constant like miss seems to smooth out a bit when I floor it but still seems not t have the power it should. At idle it is noticable and I know something isnt right. I checked the coils and they look ok and I installed new champion plugs gapped at .35, with no change. No codes come on for misfires but maybe its not triggering one idk. I talked the the parts guy at jag and theres no way in hell im paying 400+ per coil on a maybe it will work.

The other real annoying thing is the tras seems to shift erratically and the lock up converter will not lock sometimes which does create a code. but once I clear it it drives fine but the trans still feels a bit awkward an I dont know why today these codes showed up

P0132 still dont know what to look for with that code

P0304 dont know this one first time it showed up

P0743 this one showed up with the one below

P1775 this one is for trans but after clearing it worked fine.

I need to get this going well asap as someone hit and destroyed my other car in the last snow storm you guys are my only hope. Im a mechanic but I am use to newer cars that will tell me what to look for and I suppose its spoiled me lol.
