i didnt get the code yet? hmm that makes sense

on wed im going to devo il get the car checked up

check the pump

check acd

check abs wheel speed sensors

 

Abs sensor is not....engine check turned on thou...wasnt exhasut related i bet

 

i have a feeling its Acd transfer case

either

-little fluid

-bad pump

since when the car turns its using the acd more and thats where it goes worng and seems like it locks up

that would make sense

 

hmmm... true.

I really don't think it's the pump though. Lets say the ACD was going into lock-up causing the issues while steering... the ACD only locks up when the pump is on. So if the turning issues are from the ACD then it's a bad sensor of sorts.

The other thing i'm thinking for the turning issue is a bad front diff that is locking up when he takes sharp left turns, but that doesn't explain the ACD malfunction unless the computer knows the front diff is messed up and turns the ACD off to save it.

I guess we'll find out on Wednesday.

Post up what it is, don't leave us guessing.

 

I think you are mistaken on how the ACD works. The ACD only engages when it senses slip on wheels, and only locks up the center differential. this has nothing to do with turning unless you are accelerating while turning enough to slip / slide which you shouldn't be doing if your car is having these issues.

Under normal driving where the tires are not slipping the ACD is not doing anything.

 

yeah i have no clue rite now

ill post it up on wed

ill know for sure

i hope it's notihng bad

 

I have the same problem
some times when i start the car the 3 light gose on, I wait for the car to warm up than I turn it off than start it again, and it's back to normal, only one light in on Tarmac.
Dose that have to do with the pump? or something eles??

 

i have no clue yet i checked i have all my fluid....so idk either it doesnt... the pump dosent work...


or someitnhg else is messed up..

 

You may have messed up your mass airflow sensor. Did you recently do anything with the air intake system? Turns out the ACD, Evap Emissions and Barometric Sensors are all on the same circuit as the mass air sensor, and if one goes out the ECU will throw all of the codes. When the Service Engine Soon light goes on, all three of the ACD lights are on.

I just had a problem like this recently, and the tech at the dealer figured it out after much tinkering and testing. New MAS on order, and problem is solved. Just another thought. This wouldn't explain the strange turning, but the erratic idle could definitely have something to do with the MAS.

 

same thing here bro, happened after i replaced my clutch.

that is retarded, why the h*ll would MMC do that.

i think this is what is going on in my car because i was still able to take a corner at high speed and keep traction without, other than having 3 annoying lights on my ACD sometimes, the car drives fine.

 

have u checked the CV boot on ur driver's side axle? since the trans faces that way, it might be spinning too fast causing the front LSD to lock late, but i would check the other stuff mentioned above as well.

diff fluid check
ABS sensor
scan tool for the code
driver's side wheel bearing
drivers side CV boot
driver's side axle (in case it might be coming out)!

 

why are evo owners so cheap? just go to your local evo specialists (stealership) and have them figure it out...if the job costs too much take it somewhere else! at least you'll know what the prob is to get fixed! quit ranting and fix it already

 

Davethewave,
You really should have the dealer check your MAS. If you car ever runs erratic it could definitely be that. I had mine replaced finally yesterday, and it runs smooth again, and all lights are normal again.

If you are getting a check engine light along with the three ACD lights, go to Autozone and have them tell you the codes. If it says something like "Barometric Pressure Sensor - Circuit Low" then it very well may be the mass air sensor malfunctioning and causing codes to show up along that circuit. Mine showed three codes: Barometric Pressure Sensor, Evaporative Emissions Sensor and Throttle Position Sensor.

The reason I knew it was something else was that the car was driving pretty totally normal (except for erratic idle at times) but was throwing a throttle position sensor code - it didn't make any sense. The tech at the dealer confirmed it was the mass air sensor and ordered a new on under warranty. Problem solved and the car runs terrific now!

 

so update on us on the info what what was the problem????

 

i forgot to tell you guys what happened everyoen wondered

so after my engine was built 2 silly things were forgoten

notihng big

imagine engine harnesses

2 clips were missing thats it

and thats y the car behaved like that

it was 1 minute fix its all good now


dont forget the clips ppl
