p0307 cylinder 7 misfire my car is throwing this code. it is also throwing the p0133, p0153, p1134, and p01154. i know these codes go with my o2 sensors, bank 1 and bank 2, sensor 1 and sensor 1. i've got new gm o2's coming. i checked the plugs, plug wires, and the coil for cylinder 7. everything is fine. can the o2 codes be causing the p0307 code? also i am installing a racetronix fuel pump this friday because my stocker is going bad, making a bad bad whinning sound. do you all have any suggestions? thanks.

Some cars tend to be picky, had a similar problem you might want to check your O2 extensions, make sure that their not pinched or cut. Also check and see if the O2 sensors are threaded in right, and all the way into the header. 
You might be running rich wich sometimes causes the sensors to foul out.
