Under the Engine module, check Measuring Blocks and find the block that displays Intake Air Temperature. The reading will be displayed in degrees Celsius. If this reading is much different than ambient (assuming the engine is cold and not running) then try replacing the Intake Air Temp sensor:

See if that helps at all. Also while the engine is running check the Measuring Block with Mass Air (MAF) readings. If you're able to drive while logging, you can log your MAF numbers while under full throttle. The MAF numbers should exceed 100 g/s at full throttle above maybe 4500 RPM, and if they fall pretty short of that you may want to at least clean the MAF sensor, if not replace it.

 

alright ill record some data on my way to work tomorrow, check back in a day or 2, thanks!

one more thing, both my oil temp and engine temp, always at the minimum level when im driving around, besides when i idle after warming it does the engine temp go to middle level, oil never changes, stays at minimum.

thanks agian!

 

Looks to me like at least one of your O2 sensors is junk as well. Assuming they're probably original, it couldn't hurt to replace them anyway.

As for the coolant temp gauge: What does your coolant look like? The coolant temp sensor that sends the signal to that gauge is in a plastic flange on the back of the cylinder head. However, usually when it goes bad it gives very erratic readings, not consistently low readings. It's possible that your t-stat is stuck open, causing the coolant to take much longer to get up to temp. If you let the car idle for longer than normal, does the coolant temp gauge ever get hotter than the center line?

I've never heard of an oil temp sender going bad but that doesn't mean it can't happen. I'm looking through my Haynes now to figure out where the **** it is lol

 

getting a 147 Celsius temperature when car is off, 146 when at idle cold start. im assuming thats the bad intake sensor and ambient temp is sayin 46 celcius.

at idle mass air flow readings are 3.3 - 3.6 no higher then 4.0 gs

coolant is a bit cloudy, red in color. and its not that its constantly low, when at a stop light or sum thing it will reach middle 90 degrees, then i start driving go to minimum 60 degrees, oil temp is whats constantly low, from a cold start to warm temp never moves,

heres the logs of mass air flow to rpms top half is city, bottom is highway,

Your MAF readings look pretty reasonable. Definitely replace that intake temp sensor. And it sounds like your thermostat needs to be replaced.

 

Thanks for posting the link and the support!
