So I went out to Portland International Raceway to test out their new track with my 8. It was a lot of fun, but I came to a problem halfway through my 2nd session. I took a turn sharply and the car started to slide out but the traction control kicked in and straightened out (not like anything unusual). But, shortly after that, my battery light came on, I got a CEL for P0113 (IAT High flow circuit), and my TCS light (car with curvy lines) is now on. The car still runs normally, idles normally, sounds normal. Now I did my searching for the IAT and disconnected my battery and cleaned my MAF and IAT with electrical cleaner. I thought it might solve it, but I think my MAF might need replacing, it didn't look to good. But would that have set my battery light to go on too? And what about the TCS light?

BTW, the only mods I have is the battery relocated to the trunk and exhaust. I checked the battery connection and it looked good.

 

I'm guessing loose battery cable(s).

The steering alarm is the 'tell', it being an electric system, doesn't like even brief power outages.

Tighten the terminals, and the grounds. Reset the steering (all the way right/left/right/).

alright I'll take a look and give it a try! Thanks!

 

So I looked at all the grounds I could get to, and they all were tight. I came to a problem today, I was at a traffic light, stopped and just idling around 750-800 RPM. While looking at my RPM's it dropped down to about 250 but went right back up to 1000 then down to 800. MAF problem? I took a couple shots of my MAF sensor and it looks like it was melted, maybe too much hot air? I can't really look at the wires down in the cylinder (don't have any good bright light around), but the IAT looks good. Sorry about the pic quality, camera phones suck.

 

Looks like you got oil into the intake. The senor is black but can be cleaned with rubbing alcohol and cotton tip.

Unplug the hose from the oil spot at the MAF tube.

Plug the hole with a rubber plug. Attach a filet on to the end of the rubber hose.

Clean the MAF tube.

Re set the ECU. Drive a few cycles for the ECU to learn.

Looks like you did most of the above.

The TCS light came on because you drove like a MAD MAN.

 

If the input voltage is more tha 4.8 volts the PCM will throw the cell P0113

Check your wiring for a short or open circuit.

Battery light may come on if you almost stall out.

I assume it did not stay on.

 

I need to clean the tube, maybe I'll try to use some rubbing alcohol on the IAT and see if tat does anything.




Now I don't know mcuh about the wiring side of the cars (time to learn). What's the best way to check for a short? And the battery light has been on ever since. I used a battery tester and it says it still has a good charge.
