I was on my way back home on the interstate in my 2003 G35, 5AT sedan when the engine starts loosing power and sputters and stall out. Luckily, I can pull over and put on the hazards. I attempt to start the car about 10 times. I will start, but then it immediately stalls out. I sit for a couple minutes and it starts up and I cross my fingers and complete the rest of the 8 miles back home, as the nearest shop is closed by now and too far away. The car has 82K. I have had it about 4k miles, bought it the beginning on January. Has anyone had this happen. I have never experienced this before...it was as if the engine wasn't getting enough gas??? I only put premium in the car.

There is no check engine light or any other warning.Clogged injectors, fuel fliter...what gives; any guesses?

 

I am at the shop and am being told that the mass flow sensor went bad and was dumping too much gas. I guess thats why it was sputtering! Air filter was soaked with gas. Looks like I will be out almost $800.[/LIST]

 

ouch sorry to hear about that, hope you can fix it asap. Did they tell you how the mass flow sensor went bad?

 

Try to clean it first. You can buy a can of MAF cleaner for ~$6.
