Severe Power Loss.

[KezR33]

So I'm driving to my girlfriend's house tonight. I'm accelerating up a rather steep hill in third, when at about 3000rpm my car suddenly loses all power. It's like it hit a rev limiter at 3000rpm. The exhaust starts making a loud, rapid popping noise and the car shudders slightly.

It scared the shit out of me. The car drives fine otherwise, but you push it even slightly and the same problem occures.

Any idea what's going on? Thanks.

Sounds like an ignition problem. Check your plugs/leads/ignition coils.

There is also a possibility you could be using low octane/tainted fuel (mate of mine had a similar problem with his Maxima as you described, he drove it was nearly empty and re-fueled - problem went away).

hmmm.. wot about your afm? if the plug has come out doesnt it barely get over 3 grand? and its "like theres a rev limiter at 3000rpm"

just a thought...

cuz if the car has gone blind in the amount of air its sucking in, I believe it would cough and splutter or possibly even shudder as you said... and the poping may be the fuel ratio getting too rich/lean... cuz the car has gone off the standard air/fuel maps and has gone crazy:P

Exact same thing happened to me,

RB25DE issue.

Spark plugs and Coils are your best bet, the car will shudder non stop as soon as you hit over 2500 or 3000 rpm.

It happened to me last week and freaked me out, got new platinum sparks and splitfire coils.

Works a treat !!

Is there anyway to test these things, or do you have to just buy it and hope?

I think I'm just gonna have to hand it over to my mechanic.

[SHANE666]

im pretty sure a mechanic can check if coils and plugs are delivering enough 'spark'

whered you get your platinum's from vicky?

Plats were provided by DRC in Greenacre man, his a good bloke, Gil's his name director of DRC.

I called him up basically after telling him ive been reading and told him what the symptoms were, and his like yup. Sparks are gone, and known hassle is coils, one of fix !

I was like hektik!! i bought the coils, and he supplied the plats and full service.

Anyways, Kez, trust me bruh, when u goto ur mechanic and just get ur sparks done, then find out it doesnt fix it, then you gotta go hunt down splitfire coils, then go back to him and get charged again to get them into the RB25, its a mad headache ripping the top end off to just get into the god damn sparks and coils -.-

I was smart though, when i took it to DRC, i told Gil i need the car in 2 hours, he got 2 mechanics to work on it, and was done in less den an hour and a half. sweeettt!!

Trust me, you wanna go the full 9 yards once your in there, so might aswell mod it now, and tick that one out of your lil Holy Mod Book!

But yeah, i saw a coil replacement guide on here, just a few threads below this one, you COULD do it yourself and save the labour costs, but in my opinion i would just get it down to a garage, not a normal petrol station garage, take it to one that knows their S**T bout' imports.
