Idle issue please help.

[rb__life]

I have a 1996 R33 RB25det.

 

I recently replaced rocker cover gaskets and once everything was back together when I turned the car on it has a really rough idle then with in 5-10 sec engine stalls.

Can anyone point me to the right direction

I have put everything back as it was and have double checked everything. Car was running mint before I did this.

Idles Roughly under 1,000rpm before cuts.

 

Note - car has been parked up the last 2 weeks. I was kinda just been changing gaskets in between work and spare time.

You have a vacuum leak.

You have a vacuum leak.

I thought as much. But I've checked it and can't see where. Are there any tips checking for leaks?

If the engine is running, spray carby cleaner or similar at possible leak spots.  If you find the leak the revs will change as you replace air with fuel.

If the engine is not able to run, you do a pressure test and look for outward leaks.  Do a search on here for a howto.  Has to have been covered more times than a Kardashian wedding.

Cheers. Thanks for that. I'll get on to it.
