Eric,
Thanks for your help, i think you are right. I am going to first fix a leaks in the exhaust i found. If this doesn address it i will move to changing both o2 sensors. Thanks, Andres

Actually some of your problem could be vacuum leak. So yeah, fix the exhaust before you replace the O2 sensors.

So here is the update, after fixing said leak i drove around for about a day. During that time frame the SES light went off, and the next day it came back on. The only two things that changed was the fact that i put gas in the car, and that the weather got significantly cooler and dryer. Hence, i am now leaning towards me needing to replace the oxygen sensors (upstream). Thoughts?

27BB AND 27BA -- Fuel system Lambda 2722 Fuel-pressure sensor, signal 2786 Plausibility, fuel-pressure sensor, to mechanical pressure regulator 2B3B and 2B48 cyl. 7 misfire and exhaust We replaced the cyl. coil to address the misfire. The shop is telling me that the fuel pump control unit has gone out. It has been ordered and it should arrive today or tomorrow. I am tempted to swith the low pressure fuel sensor before the more expensive control unit. Thoughts?
