Jeremy's R33 Issue (Splutter)

[RosieR34]

Hey Guys,

I thought instead of going off topic in the selling thread, I'd thought I'd create my own.

So after a few SAU members giving their wisdom and a few of my mates we've tried the following.

1. Cleaned Airflow

2. Lowered boost (also raised)

3. changed coilpacks

4. restarted ECU

5. Spark plugs replaced as of 3 weeks ago*

6. Did everything else I could think of (cleaned bits and pieces)

The issue is still there; spluttering at 3,000-4,000 RPM.

On a few of the tests (low boost) I was getting the following response from the engine. 2nd gear take off

4,000 RPM; splutter inaitated,

4,000-4,500 RPM engine was fine up until 6,000 RPM (Gear change).

3rd gear was a little better (Not spluttering until 4,500-5,000.

*Spoke to my friend a moment ago, and he found this on the Tubes.

(same issue)

The result was not using the correct spark plug. The guy who I bought the car off did some testings to fix the issue and said he changed the plugs and belt (+ other things). I'm guessing he put in the wrong plugs or something.

So, for my next adventure - I will be buying some plugs and testing them. Fingers cross this is what fixes it.

Will post update and possibly a videos.

I'd like to give a huge shoutout to Rob for helping me in person with supplying parts and giving advice over the phone whilst I was leaning over the bonnet and a shoutout to Brad for his knowledge in the other thread / via PM. Also, a shoutout to everyone else on SAU for giving their 2cents; everyone said it was sparkplugs from the start, but given that they had been changed before purchase, I thought it wasn't the issue.

[Anfanee]

did you gap the spark plugs? or just shove them in. If you didnt change the gap that could be your issue.

[Got a Pulsar]

Borrow my plugs 0.8 gap and try before you buy.

[RosieR34]

I haven't touched the plugs yet.

They're fairly cheap nowadays Rob, cheers though !

I'll have to take your coilpacks back out and the plugs if it fixes the issue. So, I'll spend some dollar and test it.

Spark plugs were the first suggestions by many, but disregarded due to them being new (apparently) whether or not they are the correct plugs is unknown. So, I'll buy them, try them and hope it works. I want this problem solved finally

When I get home from work I'll be working on it with my brother in law and hopefully when I swing by again Rob, I can return your parts. If the plugs fail, may have to hook it up to your snazy computer.

[Anfanee]

Don't get new plugs. If these plugs are new take them out and get a spacer as rob said and tap them down. You have to top all plugs down to .8 when you buy them for a skyline.

[RosieR34]

Oh, they don't come as 0.8?

(I didn't buy these plugs, they were purchased a week before me buying the skyline).

When you refer to "gapping" is that something I purchase or a garage job?

(I'm still learning lots about cars )

haha, hang on ill find some pics to help

Basically you bend the metal bit at the end to have a smaller gap .8 is what dielines use. All you need is a tool to change the gap and you are all good.

Its really easy. I did mine by getting a metal plate gaping tool and gently tapping them on a brick. But i would recommend one of those round tools if anyone has one.

also this is what you are changing:

Let me know if that helps.

[Brad54]

Nice work man. Looks like you've already done quite a bit of trouble-shooting!

The video you linked definitely doesn't sound like engine cut due to overboosting, so I'm going to jump on the spark plug bandwagon too!

Be sure to keep us updated and I hope you get it sorted out.

[Anfanee]

also jeremy are you north or south side? Either way im south and Rob (Not a pulsar) is north and im sure he would be willing to lend a hand (I usually offer a case of beer) to do it. its literally a 5 minute job (Max).

[Got a Pulsar]

Yep we are both in Dunlop.

Seriously Jeremy, I have my old plugs, pre gapped from factory to 0.8 and they work fine.

You can have them for FREE!!!

NGK BC.........6 BLAH Can't remember the number but they are the correct ones and they work.

Edit: oops, it was Anthony I msissed ! So, thanks to Anthony ! haha

I can safetly say, if it ever happens again or happens to someone else, I can point them in the right direction ! It's a pain in the bum when trying to kick it, or even go for the famous "Form One Lanes" at the lights):

I'm on the northside - about 2 minutes from Rob !

Rob has already offered me his services plentiful times, which I am extremely greatful for; really nice bloke and always keen to help.

p.s I'm yet to post in the "Spotted !" thread that I saw a 4 door Skyline

Tonights project will be gapping ! Will get some pics and video of before and after.

lol No worries Jeremy, but the shoutout was already in your 1st post i think! ;P

Glad you thought I could help, even if it didn't really solve your issue.

On another note, do you have any pics of your car somewhere?

*EDIT* never mind just saw your intro thread from the other day, shame about repairs needed but I love the colour! It'll be hard to miss you driving around in this!

And a belated welcome to you!

Haha, yeah, I forgot the shoutout was for Anthony

I only got carsales pic ): Which will be updated hopefully tonight.

You can hear me coming AND see me coming ! (Exhaust is at 99 dB)

Depends with future projects, but I was thinking a matte black spray. I haven't seen any in Canberra (Whether or not that's a good or bad thing).

[Trozzle]

Just a thought - I haven't read anywhere (that I noticed) whether your car is a series 1 or series 2. Which is it?

[Got a Pulsar]

2 but 1.5 I think

it has s2 engine, bonnet, steering wheel but no passenger airbag and s1 interior...

Thinking 1.5.

A series 2 (1.5). I buy series 2 parts.

[Trozzle]

Fair enough, was going to suggest simply swapping out the ignitor pack before you worry about coilpacks or spark plugs haha....but you don't have an ignitor
