I have an 94 GTR I am having hesitation and loss of power with under throttle. Driving on the highway it would lose all power and slow down then all the sudden have power again.

It will also not rev over 4500 RPM without jerking and RPM jumping around a lot.

I have replaced:

Injectors (have 3000kms on them since replaced)

Spark plugs

one MAFS (was getting a mafs error and replaced one then it cleared)

checked coils all were at 1.2 ohms (was a crappy multimeter the probes had about a .4-.5 resistance)

I am stumped as to what it could be I am running a stock tune with nistune just set for larger injectors.

I am going to look into getting an igniter pack wondering if anyone else had any ideas.

Okay so i wrote down what my car was doing as I took it for a drive. Only seems to have problems under full throttle in first gear @ 4500-5000RPM second @ 5500-6000RPM and doesn't seem to have problems in third. So I think it only has problems depending on the load? The EGT (cat sensor or whatever) light did come on when I was having running problems my air fuel ratios are good aswell. Maybe my ecu is retarding the timing?

Welcome to SAU Nathyne :rolleyes: - preferably under better circumstances.

Process of elimination...

Plugs tick > 1x AFM tick (but what about the other one?) > Coilpacks tick (but are there any scorch marks even if faint? tried wrapping electrical tape around each one or swapping with someone else's?) > Looms (are they old/stiff/hard/inflexible) > ECU

When you've sorted it out, don't forget this...

"Stock tune" doesn't necessarily suit every car. I would suggest getting it onto a dyno and tuned properly.

Fuel ratios are good it ran over 3000kms perfectly on this tune I don't think that's the problem. My car is stock except intake exhaust and the injectors so a "stock tune" should run my car no problems.

      Who has a Infiniti Q60, Q50 (V37)?

      Yep, it was only an option on the Q50 Hybrid.  Same in Japan as far as I know. And doesn't use a centre diff like the Suby's do, so not the same as the WRX.  But it also isn't a reactive AWD like other Nissan AWD vehicles are, eg. Murano/Xtrail/etc.

      You should have got a Maine Coone then. Only thing is they're big. But so cool, and just like a dog. Or, just get yourself a high performance dog. That'll teach you for wanting Parkour indoors 😛

      Are you thinking of Bens R32? I don't remember if his went through the bonnet itself, but it went through the chassis rail. Brad (RISKIN) bought it, and turned it into a track car. It's funny how anti people are of Jim Berry now. I remember when I pulled mine out (during an engine change) and inspected it and found it cracking badly. At that point in time so many people were even on SAU, were so pro Jim Berry, and that was after Bens GTR exploded his quite publically.

      That's one of the reasons I got that breed, they look weird, the other reasons are they small, they are very vocal, and run around like they are on crack, I didn't want a breed that just sits around, these two are like kids on red cordial  My daughter has one, and it's a laugh riot, constantly doing Parkour around the house, sits on her shoulder, plays catch, and constantly runs around the house taking turns chasing the dog around, her Bermese though, just lays around with constant bitch face, and just looks on in utter disgust at the cat and dog playing together

      I'm getting PTSD flashbacks seeing that name again.  With my turbo swift, I got 1,500km of street use on a Jim Berry clutch before it exploded and took out my input shaft with it.
