Agreed on both your posts above, good advise. +repAlso is bad to run without thermostat, ill take to long to heat up to operating temp and cause a check engine light, then 02 sensors this car is picky if you cant afford a new one find someone parting out same car make sure you get the right one there all different, short ram intakes are not very affective on our cars since we have a well sophisticated cai from the factory your only best upgrade would be the srt.
Hi. Yes, unmetered air or a vacuum leak are common causes of running lean. It's pretty hard to get an actual shot of the bay vacuum lines because the intake manifold covers most and they sit down in between the runners. There's a reserve tank for the ACIS and many connections are not clamped at all. Unmetered airflow can cause the car to run lean, so verify there are no leaks between the MAF and throttle body. Make sure the throttle body gasket is in good shape, no cracks, obviously. Sewell has these vacuum lines pretty well played out. Remember you have piping there for gas tank pressure regulation as well as vacuum lines into the intake side and for the ACIS. Hope this helps, see the link for a description of the parts.hi..
jason you say that .. Things to check for causes of both lean DTC's....
-air induction system(any vacuum leaks, check near firewall driver side?
but exactly where find vaccum leak. you can post a pic?
Any advanced obd2 scanner will usually work, as well as a techstream 2.0 the dealers use.huh?? how do you guys know whats going on? I feel like i'm trying to read brail in shorthand... lol
To see both banks like that tells me it could still be MAF related, fuel pressure related, vacuum issue or unmetered air. Try setting the parking brake and put one foot firmly on the brake pedal and then try to give it some gas to see if you can achieve a calculated load of near 75% or higher. If it doesnt go above 50-60% your MAF may not be reading airflow right, which is the reason I posted the airflow specs straight from the DI book.here post the log frezze frame by torque

my value of the engine load isYou rang? Lol
I see a few things that are concerning. Look at the specs I have for intake air speed and calculated load, yours look low. See the third chart up, at about 1000 rpms you have a 0.7g/sec flow rate, all other times it's 3g/s or lower. Spec is 3.5-5g/s. At 3k rpms it should be 12.5-17.9g/sec.
Also your calculated load is low compared to the specs I posted, try setting the parking brakes and push the gas and hold the brake pedal and see if you can achieve a calculated load value higher than 75%. At idle it should be at least 15.6% and you are way low. This could simply mean the MAF needs cleaned or is faulty in my opinion, both calculated load and intake air speed is majority relied on the MAF.
