I have posted about this before and have come to no resolution. My G will cold start fine. But if I drive it around and let it sit for 20 mins it will bog out and stall if I do not give it gas. I have had the fuel lines checked and the idle reset at infiniti twice. I am now throwing CEL, SLIP, VDC OFF and basically all my lights.

I currently had a CAI, M370, High flow cats and an axle back. I brought it to infiniti for the VDC and SLIP and they said new pads and rotors and now are saying the boging was due to my throttle bodies needing to be replaced. Any ideas. Car has 75,000.

Any help would be great. I am thinking about getting the EPS throttle bodies but would that just be a waste and throw more codes? I have emissions in 1 month.

 

Whenever one adds non OEM parts to a vehicle it makes troubleshooting a problem much more difficult.
Perhaps you have a clogged/defective catalytic convertor problem?
Remove all your mods & go from there.

Have you tried cleaning your throttle bodies? There is a DIY on this, read it carefully before attempting. I would do this before the replacing like the dealership suggested.

 

I had cleaned them when I had installed the M370 manifold. This has been happening since 2 days after I bought the car bone stock at 50,000 miles 2.5 years ago. All the other lights are new but then dealer said that was related to the brakes.

 

Did you reconnect all the lines when you put the new manifold on. Also make sure you use new gaskets on throttle body and don't over torque the bolts down

 

I run into this problem almost every time I go out for lunch at work, which is once a week. I crank, let it warm up, drive for five minutes to the restaurant, and once I get back in to crank again the rpm's just drop way to low and it stalls on me. I crank again and sometimes I won't have to do anything, other times I have to give it alittle gas. This all started to happen after I installed my gen3's. My HFC will be here tomorrow and I'm tuning with Z1 next month so I'm hoping the tune and removal of my old cats(which are bad) will solve the issue.

 

Have you checked what codes are thrown when this happens?

Sound awfully like a cam or crank position sensor issue.

 

when you put on the CAI did you make sure to keep the sensors oriented in the right direction and keep them clean?
