I have a 95 civic coupe dx and I have an AEM intake on it (some of you may remember this story). I went through a flooded section of a road and the intake sucked up so much water so fast I threw a rod. I replaced the longblock but the car still doesn't run right. My intake is new so the only thing that would still be damaged would be something on the Throttle body or exhaust manifold. My computer threw a IAT sensor code so I'm waiting on that part from Honda, but is there anyhting else I might need to check that might have been hurt from water passing through it???

 

Am I reading the codes wrong? I replaced the IAT sensor (which I thought was on the TB but I guess it's on the side of the intake) and the problem is still occuring. The car starts up and idles but pulses as soon as you hit the gas. You can rev past it but there is something wrong here and the computer is still giving me one long flash, a 10??? What's the problem here???

 

Just had a thought, maybe the code was a 1 instead of a 10. O2 sensor makes sense. Would it make the car perform like that??? How long are the dashes when your reading the trouble codes?

I just watched the video on checking codes on a 92-95 civic though, and the flash seems pretty long, like a ten. And the problem happens with the O2 sensor plugged in or disconnected.
