Think it needed cleaning? lol lol

them exhaust brakes sure do dirty em up! I would clean at each oil change.

I'm going to clean it atleast at every oil change. Might just clean it once a month. Was going to clean my MAP Sensor but couldn't find my deep socket :argh:

Overhead POS has went up 4-5 mpg. I'll hand calculate it next time I refuel.

What does this sensor do?:stupidme:

IAT-Intake Air Temp.

Has to do with the fuel mix, if it is dirty it wont read right and the result can be bad mileage

I clean mine every 10k......looks just like that too, and when cleaned it idles like a purring kitten

it reads the air temp at the plenum of the head. In cold weather it triggers the grid heaters and richens the fuel mix. This sensor is only effective during times of low boost. After the charger lights = > 10psi its all in the box actually pretty crude a well tuned 12 valve with a perfectly adjusted plate could actually run cleaner. I belive the ADR box is a big step as it is tunable throughout the fuel curve

:c:Do i have one of those on my 96 12V? and where would it be located and how do i take it out and clean it???? Thanks in advance!:c:

Yes you do

Throttle response has improved. I now notice that on my Pulse the IAT and Coolent Temp match at startup now.

hmmm, i know what im doing today

cleaned the IAT today and recalibrated the APPS. very nice difference. KDP kit goes in tommorrow!:yeah:

Yuck. Guess I know what I am doing this weekend... 150K and never been cleaned. Will have to take pics if I can get it out. MAP sensor will have to come out too if I am going to go to that much work:tttt:

wow i havent done mine 112k it coming out for a cleaning

Its gonna be Nasty

Thanks for the diagram, def cleaning that this weekend

shoot, it only took me about 10 minutes to take it out, clean it, put it back in, toughest part is getting to the damn thing, use a deep well socket and i used a 4 inch extension to get mine off, when you put it back in, no more then 10-15 lbs of torque, otherwise you could crack that aluminum threads
