Drove without my IAT sensor in...

[JML97-3.8]

I cleaned my K&N this weekend and today I realized I forgot to plug in my IAT sensor, will this have hurt my car? I drove about 150 miles without plugged in. Didnt act funny or anything...

its probably not good.. but i doubt you did any damage.. and if you did.. there is not to much you can do about it now..

if the connector was unplugged i am surprised you dident get an ses light..

and if the whole sensor was removed from the air box.. you may wanna talk a look at your maf screen and see if anything got caught in it..

I guarantee you did no damage to you car. The IAT's main function is determining cold starts. The PCM compares the ECT and IAT and if they are the same, the PCM assumes a cold start and adds some extra fuel. After the engine has been started, the PCM pretty much ignores the IAT and calulates off of the ECT only.
