Help On 1998 Camaro

I NEED HELP with my camaro. first my car has bolt ons only, lid, air filter, exhaust, long tubes with catted y pipes, shift kit. The problem started last week. Car runs fine for about a mile when you first drive it and when it reaches about 170-180 degrees it starts to miss, once it reaches or passes 180 degrees it runs fine. It gives P0152,P0154 codes and p0300 for the missing. I swapped out the o2 sensors a few days ago and it is still the same, I ran it with the temperature switch disconnected and it's the same. Today after work it got worse drove for 15 miles and it missed almost the whole time, it would run good some of the time. Any body got any suggestions?

one more thing, which side is bank 1 and bank 2 on the engine

Well, you're only having problems with the passenger side, pre cat sensor. What 02's did you swap? Did you put the LTs on recently? Bank 1 is drivers side, Bank 2 is passenger side, and Sensor 1 is precat, Sensor 2 is post cat.

actually bank 1 is drivers side and bank 2 is passenger side. As far as your problem and the missing, definately check the bolts on your LT's. I had that problem because a few bolts were loose. I got a set of locking header bolts and fixed the problem. Check your spark plugs as well, pull them out and make sure your gaps didn't close. I don't believe you have a leak out your intake manifold gaskets if you didn't change it out. other than that I don't know
