2G: Total Newbie needs help with trouble codes

[Ratsel]

Hello,

I searched here and the internet, and I cannot seem to find a solution. I appologies if this has been posted before. I have these codes after I did the ignition key thing. It is for a 1995 Eagle Talon ESi with the two liter dohc engine with 190k.:

12 - Airflow sensor
11 - 11 Oxygen sensor (brand new)
13 - Intake air temperature sensor
43 - EGR (California)
55 - Idle air control valve

All of these happened at the same time. I disconnected the battery and its still the same. Is this possible? The idle is very rough & chugs(sp?), and smells very rich. Anything off idle and it acts just fine.

Also, please excuse my english & grammar, not my native tounge. Thank you.

Hello,

I checked again today. The same things are still present. Do I need to replace all the sensors listed, or could just one be causing it all? The check engine light came on yesterday (never came on before). Any help would be appreciated. Also, is there a diagram to show where all these sensors are located? Thank you.

did you run something thru your intake system like seafoam? its pretty strange that all the sensor went bad at once concerning the intake area of your car. In my opinion instead of replacing all the sensor i would test them first with a multi meter.other than that i cant really put my finger in any issue that would render them bad all at once.

Check the fuses. It looks like an electrical problem.

Fuses for the TPS, IAC, O2, AF, & EGR? I checked the fuse blocks, which dosn't list any fuses for those items. The CEL dosn't come on at all. I just checked the CEL codes when the engine was running rough the other morning. The car runs, and anything off idle it runs perfectly, lots of power.

If your throwing all thoose codes your car sounds to have an electrical problem. Parts fail but not this much.

I decided before I do anything to fill her right up with fresh fuel, after a couple corners on the road everything was back to normal. I disconnected the battery, let it alone for 10mins. Reconnected the battery, took her for a 1/2 hour drive, checked the CEL codes when I got home, none to be found. Thanks to all who helped!
