Omg Whats Happening To My Baby! Help

[SLinky-A]

Well I hope for the best aswell, so far no mods stock with an exhaust . The car is 1993 and only done 117,000km's first owner since imported from Japan by DownUnder and I rarely give it kick.

So pray for the best and I hope I don't need do a rebuilt! I'll ask them to do compression test tomorrow at KYP.

Cheers for the help mate.

Pray it's the coil pack loom

You've replaced coilpacks. ignitor, plugs and cleaned your AFM. ECU is very unlikely but it is possible.

If it's not the loom ask your local garage to do a compression test. It will give you a very clear indication if you have done a main bearing.

Your mechanic is most likely able to tell you even without a compression test.

What year model is your 32 GTR and what if any work has been done to your RB26 ?

[SLinky-A]

One more question is if the main bearing fails how is the engine still able to run?

[kawasakirider]

Not been running rich at all, using the same ones the NGK Laser Platinum that came out of the car. The coils should come today I hope! Got some yellow jacket coils. How do you fix the gap if there is one in the spark plugs?

Cheer guys!

How do you know the car isn't running rich if you can't even open an airbox or "fix" the gap on a plug?

[SLinky-A]

Because i had a mate check it out and if you read before I have done it all to the littlest thing. But still happening, so I'm getting it towed down to a garage and getting tested and finding the error.

As per my other post -

Make certain you have checked the coilpack loom. (swap with someone else)

You have so far checked

Plugs - (gapped at 0.8mm, new cheap copper ones are good)

Coilpacks

Ignitor

AFM

ECU (unlikely)

Next is

Coilpack loom

Compression test

Somebody else said it - one of your cylinders isnt firing.

[SLinky-A]

Taking to check the following things today:

Coilpack loom and

If not that than a compression test

Also is it common for the RB26 main bearings to GO?

If the main bearings goes, my car going be sitting there for months!

[ylwgtr2]

did you localise it to a certain cylinder using the method i told you to?Its really not rocket science man....let it idle pull each coil connector off until you find the one that doesnt make the car misfire anymore than it already does and there is your culprit......you need to pin point the cylinder thats misbehaving first then we can give you an indication on what to check next

[ylwgtr2]

Main bearings dont have anything to do with misfiring on one cylinder.......i assume you mean the rod end bearings,if so then you would know about it if its done a rod end bearing.....it would be knocking its tits off....

[SLinky-A]

I have followed the steps you told me to do and I did that before I installed the new yellow jackets in. However after putting the new yellow jacket coils in the car its still doing the same thing. So i towed the car to a garage to find an error. They will tell me the results tomorrow morning and i asked them if they could tell me if the main bearing has gone, but from indications of the engine he said no (thank god!!). Maybe when i was pulling the looms around to move the cover i might of damaged the wires inside and resulting in failing to work again. Btw the cylinder that wasn't working was the third one from the front of the engine.

Ok, getting my car back today and they have found what went wrong. All the steps I took changing coil, sparks and etc, might of triggered the ECU to stuff up. They found that the ECU was playing up and not sending signals to the cylinder. So the most unlikely chance of it being the ECU was the one. What a run around I tell you, just so happy it was fixed and over YAY!!

Cheers for all your help guys, wouldn't know what to you without everyones help!

What did they do to fix it?

Does this mean a simple ECU reset may have fixed the problem?

[Sinista32]

Congrats must be a good feeling.

It's not something I would have bet on as being the issue. Pleased to hear the good news.

SargeRX8 was on the ball though

[SLinky-A]

Yep, a simple ECU restart did the trick. He said it could of happened when you restarted the ECU by taking the neutral out, putting the lights on to drain the power and reconnect it back and causing a spark making the ECU to malfunction.

Cheers mate, yep it feels awesome to have the beauty back on the road. Also I 4got to add the mechanic said when he pluged his computer to scan the car, the car didn't come up with the O2 sensor registered but after restarting the ECU it was there. Should I may as well replace the O2 sensor?

Once again thank to everyone who has helped me

i have same problem dont drive it around untill you change your catalytic converter, if you want to drive it around take it off and hollow it out or else if you drive it and boot it you will put strien on your engine as i was doing untill i hollowed mien out and when i check it it was completely blocked so i had to take the honeycomb stuff out of it untill i bought my new one which came in today and installed in satourday hopefully it all goes well, hope this solves yours but defiantly sounds same problem as mine, when driving it struggles when accelerating and some smoke comes out when booting. you notice loss of power too. if it is the cat i bought a bolt on high flow 3" from justjap its called catco. so check your catalytic converter.

[frogstarc]

What should u - the casual reader - take from this? When in doubt... reset the ECU. O2 sensor is probably fine, but the ecu not seeing it b4 was probably the fault.

[SLinky-A]

I'll have a look into it mate cheers, car running fine now and at boost I don't feel no loss in power. I'm getting custom exhaust system in couple of months so I won't worry so much yet.

Cheers
