R32 Gtr Misfire

[HerGTR33]

Hi Guys,

Just looking for any help with an R32GTR which has developed a possible misfire. I say possible because it feels like a complete engine shut down for a fraction of a second, catches and runs then shuts down, catches, runs, etc...

I also doubt it being a ignition misfire or similar as you really can't make the car do it, its very random and can occur under any driving condition, on occasion if you leave the car idling it will do it once or twice, to this point it actually hasn't stalled or stopped each time it catches and returns to a normal idle.

It is most likely to occur after 15 - 20 minutes of normal city driving, the condition can last for a couple of seconds or a minute, changing driving style while it is happening doesn't change the condition, it will continue to play up on light throttle, or under accelaration.

I have chnaged the spark plugs and checked the coils, all appear ok, but like I mentioned earlier I not totally sure its actually a misfire.

Any ideas appreciated.

Thanks.
