I have a 07 G35x, ive been experiencing some problems with the car. It stalled on reverse at low speeds I have to give it more gas than usual or the car hesitates. Also when im at a complete stop the car try's to turn off and all i see in the gauges is the battery light i also have to give it more gas in order for that not to happen. Another thing is when im driving at 35-40 mph the car jumps i keep it at a steady speed but it keeps happening.
I was reading online that it could be a failing crankshaft sensor, just dont know were they are located. Has anybody had this problem before. I also get no CEL lights, i also cleaned out the MAF.

 

There is an ecm reprogram available for the hestitation/cutting off at slow speeds and at idle. Also may want to have an exhaust valve timing relearn procedure performed as well while you have it at the dealer.

 

Thank you, I will make an appointment soon, is there a charge for the reprogram?

 

Yes there is if it isn't under warranty. I would also clean your throttle bodies and reset your ECU. You can do the reset procedure or just unplug your battery for a few minutes.

 

Do you know how much i should be expecting to pay.. I have a appointment on friday morning.
I cleaned out the TB and MAF, i did the ECU reset about 2 months ago problem still came up.

 

The G is not under warranty :/

 

The reprogram is covered if it is under 80,000 miles. If not be expecting to pay around 1.0 hr. labor for the reprogram. Hope this helps brother...
