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

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!

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

Its probably the Borsh fuel pump choking on the gravy :yes:

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.

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 .

      Excuse me, but 2) does apply 1) Would also apply if you consider how much is spent in the alternatives. Also there's the option of 3), buy one pre-built that you can put your family in (it's me, it's my car)   That said, I went on a ~500km drive the other day. I didn't use anything more adventurous than 3rd/4th gear at about ~3000RPM and 50% throttle and I was going as fast as anyone has any sense doing on a public road, with enough grip to the point where I didn't want to go any faster. I was obviously under the limit of the current car etc etc. MX5 with 2.5 N/A to achieve the same speed would be more fun for any road scenario. Maybe consider cams. I wouldn't boost it. The use case is just not there and it won't actually make the car more enjoyable unless you really do plan on wringing gears from 1st to 3rd (at least) at 100% WOT on a public road to 150+kmh.

      Great if: 1. You had all of the money for everything else that is required  2. Lived in a country where you could actually do this and drive it legally on the road Sadly, neither applies to me As for the turbo, I am having second thoughts, mainly for engineering/registration legality reasons and insurance  Not saying I've finished doing stupid things that I probably should do to the MX5, but boost, and V8 engine swaps isn't on the cards Strange, but true

      Yes shipping here can be a pain, was about to purchase timing belt replacement kit, but it tends to get expensive due to shipping (and customs if importing from non-EU which the UK now falls under).
