Ok.. Here is my story so far

Get the car , runs perfect except for the 4,500- 5,500 misfire under load..

I put in a new set of plugs over the weekend, champion double platuim plugs with a 1.1 gap

Also did a oil and oil filter change on the car, Genuine filter and Repsol 5W/50 full synthetic oil.

Take the car home from doing all the work , hit the freeway and the car struggles when it gets up to around 80km/h + like it feels like someone has thrown out the ancor and im pulling it along.

Just wondering if anyone else has had this problem. Car is totally stock aswell!

Cheers

Mick

ok, i have experienced the same sort of probs before.

could be a number of things, have you installed a boost controller and been playing around with it without a proper dyno tune (as what i did)

if no then could be fuel pump shat itself, AFM, injectors, turbo leak etc. best to get it up on a dyno somewhere and find out whats happening.

Nope no boost controller or anything

Wouldnt think that it would be a fuel pump or AFM, all we did was change the plugs and oil in it..

Dont know what oil was in there before, but it must have been done by the dealer i brought it at cause it had a ryco filter on it!

      M35 Brake caliper replacement

      By Waders360 · Posted

      Hi from Canada, Both of my calipers are starting to fail. My car is a 2005 M35 Stagea ARX and I can't seem to find any parts or any cross reference caliper that would fit my car. Is there a company or a similar caliper that would fit and I could replace the OEM one. Or if anyone knows where I can find a new OEM. Any help is very appreciated. Let me know!

      S1 rb25/s14 starting problem

      By 25zenki · Posted

      Maf is a question mark but TPS  I have set at 0.47, the fact that I’m getting proper voltage range out of it with the key on leads me to believe it’s functioning properly. I’m getting proper voltages on basically everything. I still need to look up voltage ranges for z32 maf and test that

      Honestly no not at all, but it’s a very basic tune, it’s stock injectors q45 tps and z32 maf. Other than that it’s a completely stock base map. The file is from nistune and from my understanding if it was tune related I would be able to unplug maf and tps and it would still start even if it was a really shitty start. I have tried starting it with coolant temp, maf, and tps unplugged none of those 3 togethor or individually changes anything

      What does it look like with highway driving? And yes, I had a similar thought as Duncan. It looks quite similar in my Stagea and I have made myself accept it as normal. Might have to look into it some day   Highway gets as low as 10l/100km on my end so I'm not as worried about it being a mechanical issue. More likely just the tune on the haltech.
