Power cut and spluttering engine

[Willjshore]

Hi all,

 

Sorry to come straight in with a problem :/

 

I've got a 2004 350Z, modified... Custom exhaust system with sports cats, plenum spacer and up rev remap.

 

The problem:

 

Firstly it appears to happen when the car has been run hard, not for long... Today only a couple of minutes...

 

The cars power cuts out. Like if turned the ignition off, this happened while going round s round about at low revs.

 

I pulled over and started the car up again..

 

It was going along between 2k and 3.5k and the car was spluttering, the revs dropped then came back up again.

 

I pulled over again...

 

When idoling the car is spluttering almost to the point it stalls.

 

I had an engine management light for oxygen sensor 2 the other day.. I cleared it thinking it was the exhaust...

 

I've read the abbey motorsport remap bypass these sensors.. I'm at a total loss to what the problem is.

 

 

Any help is greatly appreciated so I can work on a fix.

Sounds like when I had a duff coil pack.
