Installed LTs, now cylinders wont fire right Posted this on cf, just trying to get this solved asap 
Finished installing my dynatech LT's tonight and now the passenger side cylinder bank won't fire correctly. We installed The egr tubes, and ran the headers through the stock H (deleting the cats). We also hooked up all 4 O2 sensors.
Now its spitting fuel out of the passenger side tail pipes. We tried switching O2 sensors, spark plugs, wires, and even swapped the entire coil packs. (at different times) The problem stays on the passenger side. Its throwing the codes P0300 and P0301 IIRC. It sputters during acceleration as long as the rpms are < 2500rpms. When sitting at idle, every so often the rpms would drop to 500rpm and the car would struggle to stay running. When this happened I would give it a slight rev and it would return to the usual 800rpm idle.
We're at a complete loss at to what it could be. Do any of you guys have an idea, im ready to get this thing fixed so i can go raise hell.
Thanks in advance, and sorry for the novel!
