Hi guys..

I have a weird problem, every now and then ONLY IN THE MORNING will happen once every month at least.... or maby 2 times..

My car on cold start up... will fire up but only run 5 cylinders... now ill drive it running like fkn shit all the way to work... (7:45 am )

by 5:30 6ish PM i will then go back to my car start it up and drive home on 6 cylinders.. running sweet....

problem is... i cant diagnose since i gotta go to work and at work im to busy to look at it myself... (apprentice mech)

Things to know

Recent Yellow jacket coil packs brand new

Recent Iridium plugs x6

things remaining old are the loom to the coil packs and the ignition moduel.

If any one has had this problem remember its only in the morning when the car has been sitting for ages.. in the cold also..

any help will be greatly appreciated :glare:

it may be moisute getting into the plugs on the look. try some electrical contact cleaner or some of the electrical paste you can get on all the plugs to try and improve the connection.

if you have the coil pack valley cover on then try removing it and leave it off for a few days and see what happens.

id say its moisture to. but seems like a massive amount of moisture getting in... when i cleaned my engine bay (with a shitload of water) the engine ran ruff as guts, but even after 10 mins it was fine of driving, so i dont know how a little bit of moisture getting into your plugs and not drying after getting to work, which i assume is 30 mins away? and not have it dry up...

just a thought, could it be oil leaking into the plugs? check your valley covers

It would be a good idea to test the igniter and coil plug in the morning by contact cleaning the coil plug then start it up and check. If it still runs shit clean the igniter plug, start it and doing this in the morning will ensure you've gotten rid of the moisture.

It only needs a small spray on the plug and pins to evaporate any moisture, just give the cleaner 20 seconds to fully evaporate before you plug it back in.

      There's probably an underlying issue with the A/C system too. I recently fixed mine, now it's fully control by the Haltech and car's factory HVAC controller  Have a squiz here:

      And by the way, I've also checked the ECU diagnostic numerous times and got a bad O2 sensor code and initially an Ignition Primary code, which is why I replaced the O2 sensor and all the ignition components (coil packa, plug and loom). No codes have been coming up lately despite the ongoing issue.

      Hey pber13, unfortunately still no luck. At this point the following has been done with little or no success: - Spark plugs replaced, gapped to 0.8mm - Splitfire coilpacks installed to replace originals - Replaced Ignition Coil/Coilpack harness with a new genuine nissan one - New fuel filter - Replaced AFM/MAF sensor - Injectors have been thoroughly cleaned with an online flush (without removing) - Upper engine and inlet decarbed - blew tons of black smoke out, cleared the carbon deposits from the top of the engine and exhaust.  - IACV removed and thoroughly cleaned with carburettor cleaner - O2 sensor replaced with new and genuine one -  Smoke test revealed no vacuum leaks - Healthy compression test of 160psi across all 6 cylinders Overall the car does run a lot smoother now, no backfires between gear shifts like it did originally... but the rough idle when warmed up is still there. It may not even be a misfire but simply a rough idle. Seems crazy to me that so many people have had this issue and seemingly no one has gotten to the bottom of it, or at least never bothered to post if they did! Hope you have more luck than I did pber13, I'm at a point now where I'm just going to try to ignore it unless it gets worse. Would love to fix it but I've genuinely run out of ideas of what it could be.

      I got the full frenchys kit too. Really awesome kit. Easy to install my only complaint was the hardlines I think could be routed differently (I modified mine) but I realise the kit needs to suit multiple applications. This was the hard lines before I modified them. They were touching the wastegate pipe. I ended up reducing the distance between firewall and first bend. The made it so they tucked along the frame rail.
