Hi Guys,

I have been having this issue where when I am driving my GTR32 (1992, stock) on the freeway or even suburban roads on a constant speed, the car starts stalling as there is no enough power going to it. When I put my foot down, it takes off like no one's business, which is good...only happens when I put very light weight on the accelerator while drying on a constant speed...

- I have serviced the car and changed the spark plugs, made difference for 2 days and it started again.

- I thought it was over heating, so I completely changed the coolant and it was fine for a day and started again.

- Changed and cleaned the air filters

- Changed the fuel filter and was fine again for a day

- Changed the injectors

The car stalls a bit while driving on constant speed but not as much as it feels like it is going to die.

Not sure what the problem is and I couldn't find anything else on Internet related to this. Maybe it needs tuning? could it be dirty AFM? no consistent fuel vs air? If someone could suggest something, it will be great...

Thnaks guys

what rpm do you cruise at?
Has it ever happened when you put your foot on the clutch (and the revs drop) at a set of lights or something?

Maybe when your next service is due, do a de-carb of the throttle body/top end. Most likely not the cause, but no harm done.

Nah, that has never happened.....

if im on low gear and on constant speed, it stalls and can feel it in the cabin....if im on higher gear and cruising on the freeway from 80 - 100kph, it starts and when I accelerates a bit more, it stops and starts again if i take a bit of the load off my foot again...

It is very annoying...

Maybe I will get it de-carb next time and see how it goes....

I was thinking about the coilpacks, but cant be as it only does that on a constant speed...when Im at the lights, its rpm's are fine, no drops in rpm, taking off, is fine too...

dont ever de carb nissan motor, decarb iac but not motor.

Idle Air Control valve, it controls the amount of air that enters the engine on idle, adjusting it for additional loads (Air Conditioning, etc) as well as Cold Starts.

Sometimes it gets clogged up with carbon buildup and doesn't function as it should.

It sits on the back of the intake plenum (it's about the size of a fist) and can be removed and cleaned out with a good spraying of Parts Cleaner.

Thanks heaps trent for the solution...i cleaned it in my gtr32 and it is so much more better now while driving...the amount of carbon/dirt that came out of it was unbelievable!!!! i also cleaned the air sensor for the afm's...damn it feels good driving now....

also thanks to Le-Roy for looking up the post for me...post is for rb20/25, but i got the idea of doing it on rb26...

Hey mate, i dont have a rb26 but i had the same problem with my rb20. I replaced as many things as i could. I cleaned all these parts people are telling you to clean, but after everything i finally found after trying a 3rd afm - it finally went away! Another mate had the same problem and we tried my afm on his car and it made no difference so we tried my crank agle sensor on his car and it fixed it. So basically it is a process of trial and error! But try a few different air flow meters. Hope that helps!

Two things come to mind. The first isn't applicable seeing as you've already stated that the car is stock, and that is - air/fuel ratio problems due to aftermarket atmospheric-venting blow off valves. The second, and this may be a long shot, but your transfer case may be having problems or on it's way out. I drove a GTR (not mine) once which had different size rims front and back (incompetent owner) and it was the weirdest/scariest thing I ever drove. The car would take off fine then the gear stick would jerk back and forward, and even after depressing the clutch and selecting a gear nothing would happen. The car would then stall - turns out he royally f***** his transfer case due to his intelligible wheel selection :O

    • Seat of the pants assessment of the new intake: The car is way less "doughy" when hitting the loud pedal, especially off idle when stopped or in traffic, I did use a cheapo lazer thermal thingo to measure the temp around where the pod filter got its air, it was between 55 - 60°C, in saying this the car was shut off and not moving, so the OEM intake pipe was not supplying any fresh air to where the pod was when the car was at least moving A weird bonus was induction noise on the throttle in the cabin increased a bit,  I was worried that I was actually going to lose some of that induction noise I love so much, outside though, when I got the daughter to do a WOT drive by pass for me, the induction noise has increased alot when on the throttle, not quite ITB doort, but well up there I'm extremely happy with the results and have been exploring the country roads in the region  As for house mods: 1.New front fence is up and is awesome, it really upgraded how the joint looks from the street, and the added security is nice 2. Electricians have replace some interior lights, and with more lighting in the garage, a few new motion detecting lights out the front above the garage, front room, and at the front door, which I have already found heaps helpful coming and going, also now has fancy pants CCTV all round the house The only hold point for power though is the solar and batteries due to supply issues, although this will happen over the next few weeks 3. I have done a heap of landscaping out the front and I'm almost ready to do a new small retaining wall with some nice blocks to replace the brick and cemented in rocks around the raised garden beds cemented in river stone "was the fashion at the time" the house was built. I currently have a pallet of retaining wall blocks and 2 bulka bags of 20mm blue metal to replace the wood chip that is in the raised garden beds around the house 4. I now have 3 big raised garden beds for out the back to grow some vegetables, about 70cm high, 200cm long and 100cm wide 5. My 2 compost bins are already pretty full with brown, green and kitchen waste from the landscaping I'vedone so far, but they will probably take a few months to break down, so anything else that gets chopped, trimmed, and kitchen waste will just start filling the base of the raised garden beds to about 30cm before I start throwing 40cm of good compost, and stuff, for the vegetables to grow in, I'll need a few ton of compost and soil, but the local supplier can sent me bulka bags of the stuff Basically the logs, wood chips and a few strategically placed rocks for drainage, will give the beds some good organic materials down low to break down over time, and they will hold moisture during the warmer months to save the water in my big arse water tank if we don't get alot of rain So, all in all, the car and house mods are going well, and I'm really enjoying being retired, I sleep in too 0700 and slowly plod around inside until I feel like actually doing anything, and only work in the yard for as long as want, which has actually been alot over the last few weeks,  although when you look at it, it seems that not a huge amount of work has been done,  until I look at the before I started the work pics Happy days and good times indeed 
    • hahaha yeah. Plan is to get side skirts and probably just rear pods. But going to do them one-by-one. I've got a set that I really like from RHDJapen, but that one isn't shipped to AU. So need to find someone who can get it for me
    • Here's an idea, answer the questions I asked you as they are trying to work out WHY the LSD will be binding up in a straight line.
    • You haven't driven many modern cars then have you? Most of them have sfa steering feel with their stupid electric bullshit steering systems.
