IAT sensor?
OK here goes:
I recently acquired a '91 Accord LX 5 speed.
The car has 201K miles and runs mint until warmed up. After it is warm, the check engine light comes on, it sputters and hesitates. Sometimes it stalls. This only happens when the car is warm though. The previous owner had told me that it was throwing a code for a TDC sensor. I checked timing, its dead-on. I checked myself to see what codes it was throwing and it was either throwing a code 1 or 10, Code one would be the o2 sensor, code 10 would be the IAT sensor. Would the situation described above be symptoms of a faulty IAT sensor? Or would you think it would be the o2?
Any insight on this would be greatly appreciated.

Cant remember, I'll have to check when I get home. Do you think either sensor could lead to the car running as described in the original post?

Well my car used to have the same problems before. Hesitation, stalling when idling, erratic idle, but I cleaned the air filter and most of the problems went away. However, I still have a slight hesitation in power from about 2.5k-3k rpm, so hopefully replacing the o2 sensor and clearing the CEL will fix it.
Sure, any malfunctioning sensor could cause the car to run worse.

Weird. All those problems went away from just cleaning the air filter? I'm gonna replace the air filter and fuel filter this weekend and see if that makes any difference.
Any other insight on this guys?
