2007 G-35S Sedan Computer Help

[peddydc07G35S]

I have a 2007 G-35S Sedan that I have only put Stillen air intakes and Stillen exhaust system on with no other modifications and my computer locks up way too often. Even turning off the slip control the system locks on the SLIP light and the check engine light comes on when accelerating. When it first started it was only during hard acceleration when the car shifted into 2nd gear. Now the computer locks with any hard acceleration in any gear. When the computer locks up the car shifts very hard thru the gears so you have to shut the car off to reset the computer so it will drive normally. Is there a way to turn this part of the computer off so I can drive hard without this happening??

Return the air intake to PRECISELY oem to see if the problem goes away.

You may have contaminated MAF sensor element with oil from K&N filter?

MAF is calibrated to only be accurate with oem system in front of element!

Do you mean to put the stock intakes back on so that MAF will be properly calibrated?? Do they not make an aftermakert MAF sensor that would be calibrated to the K&N filter? This problem did start when i installed the new filters that come oiled from K&N...any additional help would be great!

like the previous poster said i cannot stress enough how careful you need to be with the MAF it costs a few hundred dollars. I would advise doing the following:

1. just check is the MAF sensor removable, see if any wires are broken, be gentle..

2. place the stock intake back see if problem persists...

3. Buy a MAF sensor cleaner http://www.amazon.com/CRC-Mass...GH57G buy it local if u can so u can get to it right away, clean the hell out of it.. never ever touch any parts. poke it with the sprayer etc.....be EXTREMELY careful.... and you might want to find a way to ensure there is no excess oil on your filters... kitchen towels maybe... or something........

good luck

Don't do anything until you find out what code is making the check engine light come on. The SLIP light comes on during low traction even with VDC disabled the light still comes on to warn you the tires are breaking traction. Ignore the slip light.

Take your car to an auto parts store and have them run the codes for you. Don't make any changes until you find out what the codes are.

I bet it has nothing to do with the intake. I bet its the exhaust. I'm going to guess your rear O2 sensors don't like the increased flow and your getting Cel 0420/0430? Catalytic Converter Efficiency

If it is that code what you want to do it buy spark plug anti foulers from Autozone and space out your rear O2 sensors. Heres a link to a great walk through
