driver side missfires I did a search and I have found alot of info but I thought I would post my problem. My TA is missing on the driver side cylinders, the o2 sensors are new and the plugs and wires are new. I had the codes run at Autozone and it had a code for multiple missfires and codes for o2 and egr. I have an offroad y and the egr is deleted, but I haven't had a tune to remove the rear o2s or the egr in the pcm. The miss started when the car would warm up but it was fine when it was cold. When I replaced the plugs it misses all the time and worse when warm. The driver side plugs were fouled when I pulled them so I replaced the new o2 sensor with the old one on the driver side and unplugged the battery to clear the codes, same problem. The fuel pressure is ok and the car smells very rich. Thanks in advance!

Would help if you had your own scanner to log what the car is doing, but since you don't, the first things that come to mind are:
1) verify the plugs are gapped correctly
2) verify the plug wires "clicked" twice when you installed them
3) swap bank 1 plugs with bank 2 see if the problem follows
4) swap bank 1 plug wires with bank 2 and see if the problem follows
5) swap bank 1 O2 1 with bank 2 O2 1 and see if the problem follows
If you can't move the problem to bank 2, then you have something else going on.
