R32 Gtr Problem With Lack Of Power

[hixzoomy]

Hi people

As the title says I've got a problem with lack of power with my 93 gtr, I've done some searching on this forum and found a few things which I have already done, The problem started with fuel consumption and then lack of power and not reving over 2500rpm. The things I've done to try fix the problem so far have been new o2 sensors, and just put in new nismo afm which haven't seemed to work, apart from that the car has cat back exhaust, hks panel filter and ebc set to 14. Any help with this problem would be great.

thanks

The nismo AFMs I replaced my stockers with were a different internal diameter and required a retune of my power fc after installing. Wouldn't even idle, had to give it throttle while we backed it onto the dyno. Had your tune checked since installing? Because they are larger it will make your air/fuel ratio way out.

Get your tuner/shop to look into it. Don't get anything fixed but find out what's wrong and what it would cost to fix.

Could be a long list of things or a combination. Shouldn't take them more than an hour.

You've checked all you Intercooler piping for leaks/Splits or plain just no longer secured ?

Thanks for the advise I have checked the piping but might have missed something so I'll give it another going over tomorrow and as far as taking it back to the tuner I'm in Mt Isa so no tuners (that I trust anyway)

Stock ECU? Have you tried resetting it?

How old is the battery?

Standard ECU won't work work Nismo AFM.

Sounds like AFM problem, try a different pair of AFMs to begin with.

Agree that Nismo AFMs with standard ECU is a problem. Are you still making boost? Has the cat shit itself? (drop it off the front pipe an look in)
