i noticed this morning that the check engine light wouldnt turn off.

the car doesnt have rough idle and it still drives the same so it aint the coilpacks - ive already tested them anyway. i had this problem a few months back but when the light came on, the car had really rough idle and i pin pointed it down to one faulty coilpack so i replaced that so i dont think thats the issue.

Does anyone know what it may be? the car still performs perfectly normal but im just paranoid and rather the light be off.

Thanks for any help in advance

it wont be oil pressure, there is a separate warning light for it. the ecu is throwing and error code, run an ecu diagnostic or get someone with consult software to check them for you.

when the engine check light lit up in my car it turned out to be the O2 sensor.

      Blue slip

      By Stringycheese · Posted

      Thanks for the response. This is an 04 EP3 Type R. JDM spec. Fairly certain they're just basic BC racing coils. I do plan to keep as the ride quality on stock I've been told is pretty meh given Sydney roads. If I were to go down that avenue, does NSW require them to be a certain spec (close to original) etc?

      Should have asked what is the car?

      I've had two super conflicting experiences with blue slips. My 30 year old E39 waltzed through with no issues but my brother in law was knocked back on 12 y/o 3 series due to wiper blades and some cracking in a control arm bush.  What kind of coil overs? Do you want to keep them after?  If it was me I'd get some dirt cheap shocks and springs from eBay or scumtree. Not ideal but will get you over the line and might even be less than $1k.

      Tein Circuit Master- rebuild worth it?

      By QB6SAGR · Posted

      Hey guys,  Way back when (about 15yrs plus), I picked up a beautiful set of Tein 'Super Racing Spec Circuit Master RE' coilovers from Russman. I have legit never fitted them to my car, as it was garaged indefinitely while i bought a house Yada Yada. They look brand new! Anyway its time to pick up where I left off, and have started doing some khanacross and am booked in for a hill climb next month. The car has some hard af Nismo shocks in ATM, which has me wanting to upgrade again, and now I am left wondering if it's worth having these teins rebuilt? I think they where an ok shock back then, but how do they compare to what's on the market now?  Shockworks/mca are 2800+, and I am sure they are great. But if I can have these rebuilt and be better than, say, a set of bc's for around the cost of bc's, I would be happy with the performance v cost trade off.  If they are considered outdated and rubbish these days, so be it, I'll put them on the shelf and be happy to look at the pretty green colour while I save for the SW/MCA option. Grateful for your thoughts on the matter, and suggestions on who could do the rebuild if it's a worthwhile pursuit.  cheers, Rowdy.

      Ethanol Content Sensor - Always at 11%?

      By TurboTapin · Posted

      I can't speak for the US, but for Canada as I mentioned above, all fuel gases contain ethanol. We have regulations for E5/E10/E15. Each province handles it differently but basically any fuel gases sold must be E10 and slowly increasing to E15 by a certain year.
