Slinky Needs Help With Engine Light!

[slinky-minky]

Hi guys! I have a problem with my r34 gt-v (non turbo 2000 model)where the orange engine light comes on and stays on after 4 mins of driving(now it comes on after a minute) a mechanic got the fault code which is 21- “ignition signal primary” after taking $44 from me he told me it was a coil pack and the next day took em apart and tested them and said they were fine and charged me another $120!!! (labour)

done some of my own research and some ideas of what it could be is: COIL PACK, IGNITER UNIT/switch..... although i think the igniter units are on the coil packs in the r34’s.

so..... what would u guys do from here? How much for new coilpacks? Spitfires? Pay another mechanic to test more competently? If so who? Keep driving it until the problem is easier to find? Will this do “Warning damage to the manifold!” lol i mean engine.

Thanx in advanceJ!

Does it misfire?

same thing happened to me which place did u go to just pm me, and after that they changed the spark plugs, and that didn't fix it when i came to collect so then they reverted back to coilpacks and charged me another 140 for the coilpacks after 220 on the spark plugs -_______-

hold on... you paid 220$ for spark plugs..

Hi.

I have the same problem, though it can go days without coming on.

It usually comes on when i am taking it easy and not really boosting much (RB25DET NEO)

When the light comes on the car noticably runs a bit rougher but i usually can turn the car off and then on again and the light is cleared.

Took it to a mechanic that specializes in EFI as I head it could be a leaking fuel injector.

He got the code (I think it may have been 21?)

Changed the first coil as he said it was faulty, replaced all spark plugs,

called me to pick it up then changed his mind as light came on again,

kept my car for two weeks (which was ok as i was waiting on compliance plates)

then charged me $560.00 to which i stupidly paid at the time.

Still have problem three years later and have been reluctant to get someone to look at it again..

Has anyone heard of a leaking injector causing this?

Thanks

That doesn't sound like a leaking injector ...

Sounds like coilpacks or maybe igniter module ?

If your injectors were leaking turning the car off would not temporally fix that sounds like ignition system ...

i paid 20 for diagnostic (coilpacks - this wasn't the problem according to them)

i paid 20 for testing

i paid 20 for spark plugs

i paid 160 for 2 hours of mechanical work

adds up to 220, but the thing is, it didn't fix anything

NOW I KNOW HOW TO DO IT MYSELF!!
