Default ignition system and cold start problem

i think my Distributor might be going bad.

so i was wanting to know what distributor would you go with, given the mods i have in my sig.

and as far as why i think it is going bad is after my car sites overnight and i go to start it it falls on its face, it also depends on how cold it is on how many times it takes to start it. i ran codes got koeo 15, 85, 10 51, 96 koer i get cycle 8 has misfire but then i get code 11 so that makes no sense to me can someone please help me

i just bought a new ect for code 51 i know 15 is cause of my tuner and 85 the purge canister selonid isnt needed cause its not hooked up.

i have also cleaned the iac, done base idle reset, cleaned maf, injectors, made sure there were no vac. leaks, replaced spark plugs, fuel pump, fuel filter, cap and rotor.

also to correct the cycle 8 misfire i have swapped wires and spark plug but still no change, i would swap an injector from another cycle but would have to take the upper intake off and have to order gaskets for that.

when i pulled the old spark plug out is wasnt wet and didnt smell of fuel so would be a sign of bad injector, found replacement injector from oreilly's from a 93 cobra i believe those are 24lbs but it is $60 and i could buy all 8 from summit for 160 which would you do.

also can anyone tell me about the crane cams hi-6s with coil combo doesnt seem like bad price

so help get not lost.

am i wrong about the stock cobra injectors being 24lbs and a misfire can be caused by alot of stuff i am just trying to eliminate stuff without spending to much money. its down to injector, coil, or distributor.

fixed the cold start issue it was the fpr, but still need help with the misfire on 8
