Miss Fire From Rb25 S1

[outlawrb20det]

Hey guys after my car has been sitting for a couple of months and not driving on any roads only idling around a paint shop and car park, I decided to drive my car home to do some other work to it. When I started the car up the idle sounded alittle different. It didn't worry me until I took off on the road and it missed and stalled and wouldn't start inless foot is flat.Ok so the car will start first very well when cold and will idle well for about a minute after that it misses chases idle and sounds dreadfull.

I've done the following mods before the car about 18 months ago. Car was running beautifully.

Wolf Ecu

R34highflow

plasmaman intercooler kit

Dual stage boost

Full 3 inch

Splitfire coilpacks packs

Borsh fuel pump.

3inich metal intake.

no bov.

The car was running 16psi and never missed or carried on until now. Anybody out there ever had this problem.Or know what it could be? Thanx guys

[Hadouken]

Never have I seen such symptoms.

Me too I've had a few skylines. I checked the spark and my plugs were very dirty after only a week of moving the car around the garage. I think my coils are stuffed but wat could be causing the ignitior to kill my splitfire coilpacks. Evilness!

I was being sarcastic. Seen about 5 threads in a week alone about similar issues

[niZmO_Man]

Does the ECU use MAP or AFM?

[outlawrb20det]

My skyline uses a MAP I'm slowly narrowing it down to coil packs but I've got splitfires. I've never had a problem with them...

How fresh is the fuel

[outlawrb20det]

Fresh. 3 day's old! I'm goin to put a new fuel filter in the 33 today. If the problem is still there I'm going to clean the AAC valve and put more new plugs in.

If the misfire is still there after all that. Gap the plugs down to .8 if there not already .8

[outlawrb20det]

New fuel filter is in. The AAC is all clean. The car idles now but still missing and coughing underload.The cars now running ritch and the ignitior is very very hot. The plugs have been gaped to 0.8

Its probably the Borsh fuel pump choking on the gravy

Is it Bosch or Borscht cos it can have a huge effect.

But seriously think about checking your fuel pressure and see if your pump is still OK. Sounds a bit like fuel starvation to me.

I think I've nailed the problem

My CAS has moved.

My CAS has moved.

Hope it left a forwarding address or you're stuffed.

Is your CAS home yet?

Over a yr later I'm back on . I had 1 coil pack go and a faulty injector . Car runs like a bullet train now on boost . Now the only probly is if can take a bit to start ( pump accelerator ) and somtimes back fire on start up .  I've done a compression test . All good . So yeah bit of a timing problem .
