Hey guys,

Noticed the other day while taking the car for a lil fang at round 4.5krpm+ while on boost and full thorttle "splutter splutter" coming from the back of the car. Just wondering if anyone else has suffered this prob before? Im due for a service soon but its only a fluid one so i doubt that has anything to do with my prob. Last service (6mths ago) i had Iridiums put in so i don't think that could be the cause, maybe coilpacks? Or in need for a tune?

Thanx in advanced.

buy 6 BCPR7ES spark plugs and gap them to .7 gap. see how you go

+1 to do that. does it mainly happen when its under load as well?

it may be your coils, try taping them up with some good brand elec tap and getting new plugs gapped to like.8 or less depending on how much boost your running. works a treat.

Hows it going mate. The same problem occured in r32 when i was running higher boost levels. Tracked the problem down to the wrong spark plug. I've happened to stumble across that the xr6 turbo run NGK Iridium plug with a .6 gap. Part number is BKR6EIX. Hope this sorts out your problem.

I'll be getting a service in a couple of weeks so i'll get the mechs to do a nice once over. I doubt the plugs would be gone as they're no more then 5,000kms old. Maybe need re-gapping its true, i'll keep you guys updated...please don't be coilpacks (crosses fingers)

95% its coilpacks...

sure way to tell is tape them up..

I had the exact problem and now its fixed with tape.. sure its a bandaid solution.. but its been working for the last 9 months so far

The reason regapping the plugs work is the gap is reduced... and seeing as the spark takes the path of least resistance it sparks correctly.

      The speedo's can be very conservative, when my Mazda NC MX5 speedo is showing 118kph, the GPS, and a calibrated radar.... cop mate.....hits me at around 110kph +/- 1 or 2 kph, and that is on a 215/45 17, stock tyres size is 205/45 17 as well, so weirdly conservative with stock tyre size When my Commodore speedo red 116kph GPS had me at 110kph After doing some offset and clearance measurements to see what can fit the NC on 17x8 +40, without guard rolling or rubbing anything at my current ride height, I've decided that when my tyres are toast, I'm going to fit 225/45 17 and see where that gets me IRT actual speed of my speedo and GPS/radar From the online calculator I should be still be doing around 5kph under an actual 110kph when the speedo is showing 110kph My ADHD requires that when I'm doing 110kph on the speedo, that the actual road speed is actually really close to that, and not alot slower And going from 205 to 225 still keeps the car within the %/mm allowable in the NSW vehicle rules and regulations, which is nice, as long as I'm looking at the latest version that is.....LOL https://www.nsw.gov.au/sites/default/files/2021-02/RMS-13.464-Light-vehicle-modifications-Vehicle-Standards-Information-No-6-November-2013.pdf

      Take the value it measured as, and pick the closest range available that is above the reading on the screen.   Also, no point just testing the coils. Read what has been said again. You need to test all your wiring, everything.

      Does the scanner do all the CUs in the car, or only the ECU?

      @666DAN sorry to bring you and old thread.     I've got my de+t done and it's all running great other than 1 small issue.    Car has remained auto with the na auto and tcm, I've used a stagea ecu with. NIstune board and everything is great other than my gear selection on the dash. It illuminates park, reverse, neutral, 3rd and 2nd when selected . But nothing when in  drive or what gear your in when you pop it into tiptronic. I'm sure there is maybe 1 wire in the ecu plug I need to move to rectify this. Do ya have any ideas?     Cheers man

      Well I recently changed my rear axles and was thinking if I bumped anything, I have been driving the car for a while now though... But it has been raining today so everything is wet under the wheel arches. Brakes feel fine and can't hear any of the metal screamers, I had a squeak coming from one of the handbrake drums but that seems to have gone away a while ago. I was going down a hill when it lit up and I did feel the abs bite for a second and question why it did it?
