P0300 & P0152 Codes - What to do next?
Background:
First code I got a while back was P0406 (EGR). Before I could get to replacing the EGR valve, P0300 (multiple cylinder misfire), P0303 (cylinder 3 misfire), and P0152 (O2 sensor - bank 2, sensor 1) were added to the list.
Replaced the EGR valve and spark plugs this past weekend. No codes for about a day. Then, P0300 and P0152 back, but no more EGR code.
Between plug wires, distributor, and O2 sensor -- what should I try first?

UPDATE - Fixed
In case anyone is interested, I wanted to update this thread with what I did to fix the issues I was having with my jeep. I decided to replace the ignition coil. Easy and relatively cheap job. While I was working on the jeep, I pulled the throttle body off and blasted away 90k miles worth of gunk. No more codes the whole weekend.
