Troubleshooting mx3 codes

After doing loads of searching through these forums i am on my start to trying to understand this car. I bought it to save gas but the past few months it has gotten worse mileage than my v8 equipped Mustang. But anyways i tried the 10 and ground trick and this is how it went. Im not an expert on how to interpret these codes but it would blink and stay and then dissapear and then blink rapidly a # of times. I got 4 different sets. I believe they are : code 17 ( feedback systen leftside) code 23: 02 sensor -right side ( which 02 would that be???? the front or back sensor??) code24 feedback system (right side) and code 29 EGR solenoid valve. The bad gas mileage had me thinking the 02's were bad, also im thinking if i get new 02 sensors that may take care of code 17,23, and 24 due to the feedback sensors being close to the same.. I have emissions testing coming up soon and was just wondering if anyone could give me a hand figuring this out. Wondering if anyone else has had the same problems or can help me diagnose even furthur, and i have already checked the online manual of what the codes were. any help would be appretiated!!!

Left side is the radiator side, and right is firewall side. I believe the 17 and 24 are oxygen sensor related.

Try looking for Ford Probe V6 O2 sensors.. They are the same and cost 1/4 of the price.

The other option is to get a universal O2 sensors .Then just splice the wires yourself. that would be the least expensive route.
