Misfire ****!!! Help

[shoftw]

My friend just got this 91' sho and so far all we had are misfires.So far we replace valve cover gaskets {plug wells were full of oil} , new autolite 3924 copper plugs gapped to 0.44 and new autolite wires.

Car runs better but on cold start up misfires till it warms up and is restarted.
It runs really good down low but in 3rd gear it starts to lose power and has a hard time going past 110. My v8 sho will walk it past 80 so i know somethings wrong. I've got no check engine light on but i do have codes but for the life of me can't figure them out lol.

So i filmed them and put on youtube. so what does these codes mean and where should i look next? Thanks to who ever responds.Oh yeah probably gonna have cam sensor code because i unplugged it.

11 = pass the koeo test
it gives you those twice, then a single pulse, then moves on to the stored codes
19 = cid failure
49 = spout circuit open, timing defaulted to 10*
91 = no switching of o2 sensor, front bank

the 19 is due to the cam sensor unplugged

the 49 says either the spout jumper is missing or there is a wiring problem. the car will be seriously down on power until you fix this.

the 91 most likely means that the front o2 sensor is bad, but it could indicate a vacuum leak on the front bank somewhere.
