nismo_GTST Posted July 18, 2004 Share Posted July 18, 2004 hey guys, i've got an r33 and last week the car lost so much power. when i put the foot all the way down, it just revs and basically goes nowhere. I've tried pumping it with injector cleaner, fuel system cleaner but nothing seems to work. If anybody has any ideas as to what may be the problem, could you please let me know. Cheers, Antony.

MR R33 Posted July 18, 2004 Share Posted July 18, 2004 its something to do with the clutch in the auto or it could be the gearbox i had the same problem with mine but it was a manual as soon as it got to 4 rpm it would go straight to redline without me moving and it was because the clutch was worn and it was slipping have it checked by a mechanic Link to comment https://www.sau.com.au/forums/topic/46282-power-loss-in-my-rb25de/#findComment-940134 Share on other sites More sharing options...

ANut Posted July 28, 2004 Share Posted July 28, 2004 i have the same problem with my car. Its a 92' r32 GTS RB20DE auto. Did u find out th eproblem and how to fix it? very keen on the solution, as i am a Noob. it is my first car, and its been this way since i got it. although a bit of an increase in power as the engine warms up. Also, there seems to be a new engine noise which has just recently come up. somewhere between 2-3000rpm theres a vibrating noise, which sounds like somethings loose. Any tips on what it is or what i should do? mind you i am a Noob.

nismo_GTST Posted August 17, 2004 Author Share Posted August 17, 2004 I have taken it to a few mechanics but unfortunatly have had no luck. No one seems to know what the hell is goin on. Its got nothing to to with the gearbox, apparently, i thought it may be the coils, but its not them, the next thing thats gonna be looked at is the cat to see if its blocked or not. Either way i'll keep you guys posted. If any body out there knows of a good mechanic who knows what they are on about with skylines and are in melbourne, could you please let me know. Cheers, Antony PS. Anut, my car is exactly the same, increases in power as it warms up, sometimes it even goes back to being normal, but as soon as it gets cold, it starts all over again, and i do get that same noise around that rev range. I am trying to get to the bottom of this. Link to comment https://www.sau.com.au/forums/topic/46282-power-loss-in-my-rb25de/#findComment-982544 Share on other sites More sharing options...
Pva_Glue Posted August 17, 2004 Share Posted August 17, 2004 seems like your airflow meter is dirty or its on the way out... or it could be weather... is your fuel usage same as before? or use less or more?

nismo_GTST Posted August 17, 2004 Author Share Posted August 17, 2004 ill have the afm checked out, but i was told that if it was the afm, there would be heaps of smoke coming out of the exhuast, as for the fuel, its using heaps more, im pushing it if i can get somewhere between 250 & 300 kms from a tank using optimax. I would normally get somewhere between 450 & 500 kms Link to comment https://www.sau.com.au/forums/topic/46282-power-loss-in-my-rb25de/#findComment-982738 Share on other sites More sharing options...

Any tips on what it is or what i should do? mind you i am a Noob. Does yours make like a loud sucking noise at cold start between 2000-3000rpm BOTH when accelarating and just after when stepping off the gas? Mine does this and i've got the stock air filter and air box still, no pods (i know pod does this). And it stops doing it after the car is warmed up like at normal temp. Can there be an AFM problem, like its on its way out? nismo_GTS keep us posted wat happen to urs ok.

geordie Posted August 29, 2004 Share Posted August 29, 2004 The exhaust will make a snappy vibrating noise in N/A's and it has been layed down to a charicteristic of the engine, something along the lines of the cams, should be most prominaent around 2500-2900ish. I had a problem with mine a little while back where the engine would cut out and react like it was hitting redline fuel cut, but would do it as low as 3500rpm, esp the hotter the engine became, this turned out to be the exhaust cam sensor. Which is a mitsubishi part (Mitsu sabotage!!) i wasnt happy because the very same time it stop working, was the same time my car was sitting on the dyno, i was very pissed off. My car hit top of 96kw @ wheels, but due to the sensor cutting out at 4000rpm, and anyone with an N/A knows this is where the real power only starts to build up, i had another good 2500-2800 rpm left to pump out my power figure, i was not a happy boy.

nismo_GTST Posted September 22, 2004 Author Share Posted September 22, 2004 Hey guys. This is becoming really frustrating. The last guy i took it to doesnt have any idea whats goin on. He suspected that it might be the cat thats blocked but after putting it up on the hoist and checking out the temperature difference from one side of the cat to the other wich was only a few degrees, he said its in good nick. I am convinced that is something to do with the exhaust. Im going to change the cat anyway on the weekend and clean the pod out. Cheers P.s I really appreciate all the tips you guys have been giving me so far, thanks guys Link to comment https://www.sau.com.au/forums/topic/46282-power-loss-in-my-rb25de/#findComment-1022736 Share on other sites More sharing options...
