what brand of filter? it sounds like maybe.... (if its a wet/oil soaked type air filter like K&N) that a bit of the oil is being sucked through the afm and messing with the readings. causing rough idle/missing etc..thats my 2cents anyway

If it was wet type, he'd still have the problerm after removing the filters, is sticks on there, if it was sucking that much in, he'd have to drown the filters in oil...sure he isnt that silly ?

Give the sensor in the AFM a clean with some CRC and reset your ECU.

Running a tune ?

Air leak somewhere perhaps?

Also. Straight 5-56 CRC lubricant isn't a great idea.. everything sticks to CRC. proper way to clean an airflow metre is to take it off the car, get CRC Mass Airflow Sensor cleaner. Clean it, let it dry, and put it back on.

Maybe try borrowing someones filters to put on? Doubt it's the filters though, but that will rule that out. If that doesn't work, maybe borrow their AFM's and see if that fixes it... Just eliminate possibilities

well cars are just weird, i changed the spark plugs over with new ones seems all good now. (old ones were black)

btw im running powerfc do i need to retune since i got MINES afms?

hmm its possible the ecu may need a retune. if it comes back start at the cheapest options and work your way up from there, as stated earlier borrowing parts is a cost effective way of eliminating potential causes.

      Which model Maxima? This is good knowledge to have.

      I'm with GTS, that's not an actual overheat issue. That's an electrical issue.

      So, it's clearly an electrical problem. Either with the gauge itself, or the sender. It appears to be voltage sensitive (ie, alternator output affects the reading.

      Rb26- Enlarging Std Throttle Bodies

      Yes, at this stage of SAU threads, I  automatically assume that anyone here knows that everything depends on each and every setup and its choice of parts and what an individual wants from the setup. I think your misunderstanding what I've said, I'm not saying your curve will move to the right.. I'm stating the opposite; that my setup has a much larger turbo than my last one, my current exhaust manifold runners are 2-3x longer than the last one, the intercooler is longer and thicker (hks 103mm thick), the itbs are now oversized from 45mm up to 49mm, and the plenum is now a larger Nismo plenum that's been port matched. As a result, I'm making more power, torque and boost 1000rpm earlier than my last setup. My curve moved left, in a big way. You guys with 800-1000+hp turbos should be considering hks v-cam or the other Japanese company Sakura who makes RB25 Neo vct adaptor kits for RB26's. they all make more power / boost / torque far earlier and higher peak numbers. Dahtone Racing modifies the Hks v-cam systems to his own specs and he also developed the worlds first and best dbw individual throttle body kits, to complement his V-cam. Every single car is 800-1200+hp and they all produce huge gains in response and peak power.

      I have a 2008 Skyline 370gt with about 160,000 km on the clock currently. A while ago, I noticed the temp gauge would start climbing but it comes down when I give it some throttle. I took it into the shops. The technicians comments are transcripted below. Reported they couldn't find anything wrong with the vehicle mechanically and they pressure tested the cooling system. Funnily enough, the technician commented that the temperature dropped back down when the car is stationary but this is when I'd notice the temp gauge to be climbing. Just wondering if anyone else experienced anything similar to enlighten me? Cos at the onset, the temps were going up one tick and then comes back down when I step on it. Now, the temps are climbing all the way to the top of the gauge, and it's making me very nervous lol. It also doesn't come down to the neutral position anymore. PS I do have a small exhaust leak near the drivers side caused by when I got f**ked by a really steep driveway at a mall I never visited before. Not sure if this would affect the sensor. Technician comments: Check and verify Fan/Cooling system - ALL OK max 106*C and fans operating at 100% Cools down right away. Checked Fan Operation - 55%@101*C, 85% @ 104*C and 100% @ 105*C Vehicle did not exceed these temperatures with max load. Temperature recovered back to 99*C after fan operation while vehicle Stationary.
