well I am having strange problem basically once my car warms up and starts idleing at 600 it starts getting lower and shudders and then comes back to life it does this for a while untill it eventually stalls. sometimes if i slip it into neutral the car will stall while i am moving which isnt a big deal since i just put it back in gear. I have replaced the cts and the map sensor and have replaced as much vaccum line as i can find. I think code 34 is from where I started the car without the mad sensor plugged in By accident and the check engine light was on. idk about the rest of them. Please help the car runs awesome other than that though it is a 92 camaro with some kind of swapped in 350 looks like its from a truck or a van or something
