ok, so i have fixed the issue of the car stumbling and stalling after 20 minutes by adjusting the TPS, and replugging it in firmly has seemed to vanish the problem. Now i have some other retarded problem.

when im driving, it doesent cut out its more when u plant the foot down and gear change i cop a power cut every now and then.

is this the AFM being a Cvnt ? or is this spark plug related ?

its not anywhere near as bad as it used to be, i would love to be able to Eliminate the problem

btw its an auto.

boost is nun spec. ( stock ) LOL

plugs are ok and coil pack is fine.

i got it booked in next week for a diag, and then a service also. so if i dont figure it out by then

ill have another look at the coil packs for any wear. but other than that i could probably say my AFM is a non nissan and its buggered...

thanks defari.

oh, xD Same thing happen to my car. I changed the coilpacks and it is all fixed. The coilpacks must have cracks that allows some of the sparks leaked out. Correct me if I'm wrong but it is one of these:

Spark plugs

Spark plugs leads

Coilpacks.

Do you have a blow off valve ?

I blocked mine off which removed this problem, but along with that I also cleaned my coilpacks and siliconed them up.

Regapped plugs.

Open the AFM and check out the solder joints, if they're dry, then re-solder them.

If it occurs in gear change (meaning no load) wouldn't this remove the chance of it being a coilpack issue ?

Cooler piping, vac leaks etc.

    • The powder coating came in at $250 EACH. The TRX rims got a coat of clearcoat on the outside only.    
    • Bit wet, but YUMMY
    • Keeping in mind that I am currently getting flat 10 L/100km on my RB25DET, which means >>500km/tank. I would test this car for vacuum leaks, check codes and AFM signal with NissDataScan as D says, check plugs, do a compression check while they are out.
    • It is hard to be specific half way across the world...but it *seems* like it might have a minor issue. Is the idle stable and does it rev smoothly? I would not expect any pops out of what I am assuming is a standard ECU, standard tune, standard exhaust. You can use Nissan Data Scan to find out exactly what is happening when it runs, the cable/software is reasonably affordable if you are not planning on changing the ECU (which hopefully you are not with an NA skyline) BTW your mileage may not be that far off, these are heavy old tech cars, and being NA might mean you use a heavy foot to keep up with traffic....
    • Hey guys! Y'all are the masters so figured I'd check in on a few items here. - My engine sounds ever-so-slightly more raspy than the other NA RB25s I've listened to. It's barely noticeable but definitely a slightly different sound. - When I back off the throttle at high RPM, I will sometimes get a pop out of the exhaust, assuming this can be diagnosed as misfire. Some history on the car: - Had an exhaust leak in auction sheet but was claimed to be fixed by seller (bought from USA importer).  - Car's coil packs and sparks were replaced when it was sold to me, but unsure on what the gap is and whether the coil packs are correct.  - A prior mechanic had misdiagnosed a pilot or throwout bearing sound as LSPI/detonation. Had played with timing a bit, pops/raspy sound of engine just got worse. Got timing reset. - Had failed emissions a few times. First time went in as is, failed. Second time, replaced cat, still failed, running rich as hell. Third time replaced o2 sensor, passed. Car still smells gassy though. - Timing belt and valve cover gasket also replaced.  - Gas mileage is... low. about 350-400K per tank.  Any idea if I'm having any serious issues here or does this all sound like normal old NA RB stuff and I'm fine to drive it with the pops/slightly raspy engine? If it'll help, I can get drop a video of the sound of the engine.
