-when i turn to the left sharp car slows down by a lot like its braking

-idle is not at steady rpm varies 1500rpm up and dwon whaen driving the car in nutral

and very often rpm stays at 3k very weird

also the car feels like its messed up in the acd computer seems like it doesnt know where to distribute the tourge?

Does the car feel like the steering wheel is going to be ripped out of your hand while taking a corner? ACD pump could be messed up, or worse depending. Whats the ACD fluid level like?

ACD Fluid is in the container under the hood behind the drivers side head light, redish fluid.

Jack your car up and try to shake your wheels back and forth. You could have a really bad wheel bearing. That would only explain the ACD lights if you broke off an ABS sensor on one of the wheels which would mean you have a wheel way out of wack. I think you'd feel it while driving straight though.

Even so, before you drive anywhere do that. Otherwise your wheel could lock up and you could be s.o.l. up pretty quick.

It doesn't really make sense to me that the ACD would be causing you steering problems. If I'm not mistaken, the ACD controls the center diff which is front and rear power, not left to right which would be causing you problems when turning. Left to right torque is distributed using limited slip differentials which doesn't actually send torque one way or another, but just locks up if it senses slip.

Although I guess if your center diff were in lock-up you would feel it when you were turning.

I think you either have two different problems... one causing the turning/ACD issues and the other causing the weird idle. Or you have one messed up ECU.

My vote right now is for a messed up ABS/Wheel speed sensor. This would make the ACD fault out because it cant sense wheel slip and thinks a wheel is not spinning or is continually slipping.

What was the code from your CEL???
