so im starting to talk to myself.
anyways
after a lot of searching on rennlist site i can't quite grasp what the air temp sensor/intake temp sensor affects. mine is apparently unplugged. it can cause the engine to run rich but what other symptoms could it cause?
this is a question and for my curiosity if someone has a link to 'all about the air temp sensor' then post it.


It has very little efect on the enitre djet system, unpluged can make it runner slightly richer, actually have read that unplugging it was an old mechanics trick to richen the mixture when needed..

here is a cut and paste from THE ECU rennilist Doc.. ( alot of info there you probably just missed it)

http://members.rennlist.com/pbanders/DJetParts.htm

Intake Air Temperature Sensor

Function: Senses intake air temperature and sends signal to the ECU to provide mixture compensation.
Normal Value(s): 300 ohms @ 68 deg. F, about 100 ohms @ 122 deg. F.
Failure Modes
Open: Makes the mixture somewhat richer. Check with an ohmmeter.
Shorted: Makes the mixture somewhat leaner. Check with an ohmmeter.
Notes: The output of this sensor is used by the ECU to adjust the mixture for the intake air temperature. This is a secondary adjustment and has a small effect on the mixture. The sensor corrects for the decrease in air density with increasing temperature by leaning out the mixture. Disconnecting this sensor has the effect of richening the mixture, a common mechanic's trick.


THAK GOD for CUTTING AND PASTEING CUASE i TYPE LIKE _____!



i guess i coudln't find that its a small part in that huge wall of text on that page. but i did a google search over his whole site and none of that showed up (IMG:style_emoticons/default/sad.gif)
