Problems, with CAI

[rockfan0005]

Alright so I got my Cold air intake in today, so me and my friend tried installing it.

Well basically nothing fit (ebay typical), we pretty much made it all fit, but ran into a problem.

Of the two plugs that came out of the that plugged into the old air box filter, only one had a place to go. The other small grey one didn't.


So basically I tested it in nuetral to see if it would work. Shifting, made the engine have a huge jump between shifting, in park, reverse, nuetral and drive. (I had no idea why?)

The check engine light soon came on. We pulled the CAI out and put the stock box and filter back in.

I drove the car and it did fine after I put the stock box in, and the shifting between park, reverse, nuetral, and drive was no problem.

I have three questions:
How do you reset the Check engine light soon?

Why did the engine jump up and down?

Where do you plug the smaller light gray plug in?

THe two plugs you're dealing with are most likely the A) Intake Air Temperature Sensor and B) the MAF sensor. I'm guessing your talking about the IAT sesnor. (although an unplugged MAF would cause similar symptoms). If you noticed when you took your intake apart, the IAT sensor plugged into the rubber coupling infront of your throttle body. It has a small black unit that sits in the rubber, with a plug that plugs into it to read the temperature from the sensor. If your CAI tubing didn't have a hole for the IAT sensor, you will need to drill one to fit the IAT sensor in it; and then everything will be alright. I'm pretty sure you're talking about the IAT sensor. If you think you're talking about something else, let me know. To answer your questions:....

To reset the light, let the battery sit disconnected for 4 to 5 hours. If that doesn't do it, get your codes read at autozone and they can reset the code for you.

The engine jumped up and down with having the IAT sensor unplugged (and the same reason for having the MAF unplugged) because when either of these sensors are unplugged the PCM thinks resets to the default setting for -40 degrees Celcius for that unit. Running your car in -40 C weather = shitloads more power due to rediculously cold air; so the engine revs, shiftpoints, and tranny line pressure adjust accordingly to handle the increased power.

Thanks for the help, I put it in about 3 hours ago and it works perfectly.

The Check engine light whent off by itself yesterday after I drove it about a mile.
