Hey guys, i have been having an intermittent problem with my r33 gtst for a few weeks now. when driving along, it just stops firing on all cylinders and dies, but picks up again before it stalls. i have just replaced the coils and plugs, so i think it may be the crank sensor. has anyone ever experienced a similar problem before?? its really bugging me and any insight as to what may be wrong would be greatly appreciated :laugh:

Thanks, Bill

I too am having the same problem. My car is an R33 S2 GTST Automatic. It has been stalling while idling at the lights and in some cases takes a while to start after stalling. I have also noticed revs dropping significantly while driving and the accellerator feeling sticky when this happens. Stalled as i was taking off from the lights last night.

Car has been with the mechanics twice who have still not figured out the problem. First time in, they changed the oxy sensor which made no difference at all, 2nd time in they found a fault with the wiring harness for the air flow meter and fixed. Car ran beautifully after this for 3 to 4 hours before stalling again in idle and then 30 mins later, stalling on take off from the lights as mentioned.

My mate was with me and thinks but is not sure that it could be the crank angle sensor and from reading topic "Sticky: Missfire Boost.." it seems other people have had this problem and was solved by changing the crank angle sensor.

My advice, if it's only just started to happen, get it looked at quickly because it gets worse quick.

i'd change air flow meters over!!

LOL an engine will run without an oxygen sensor signal (though not as economically) so there is no way that would fix a stalling problem.

A missfire is not the same as what your saying you have. So i wouldnt go on anything said in the missfire thread. A common oversight people seem to have is if they have the same symptoms as another person thay automatically think its the same fault! Never assume this as 90% of the time it wont help you.

Car was originally missfiring as well and revs dropping significantly while in motion. Now I just need to work on the stalling problem. I am also running .95 - 1.02 bar. I will check the coils but I would be very appreciative if anyone has any ideas.

Thanks guys! Changed airflow meters over and so far running like a dream and better than before. I had taken this car to the mechanics 3 times before they finally said it was the AFM.

I do not recommend anyone going to Sumo Performance in Nunawading, Vic (Kamikaze's mechanics) as they had the car for over 4 weeks and couldn't nail the problem. I posted my problem here and got a response same day which was accurate and correct. Thanks again to all.

Hi everybody, thanks for the help. i took the plug out of my afm, resoldered it and car goes like a dream. I too thought it was the crank angle sensor, but had the same symptoms of stalling and funny idle. I replaced all the coils and plugs but it would just cut all power for a few seconds and then come good again. instead of changing the afm, pull the plug off, unscrew the plug body on the afm and prise off the top cover. resolder the 5? joints and reglue on top cover and screw housing back in, worked fine for me and cost nuthin.

Thanks.

Sounds like we may have had very similar problems. My wiring harness had already been fixed, plugged my AFM into another car and found it to be no good.

I found through a bit of searching on sau that cars with pods seem to have the afm break quite frequently due to vibration. when i removed my plug, the solder joints were not even joining, so much so that i just pulled the plug out of the afm. Its a bit fiddly to get that silicon off the afm, but its cheap and easy. ive since realised that is why my car has been running horribly for months. If you do a search on air flow meters you will turn up something helpful.

    • Jump into the wasteland. Plenty of random posting/chatting going on in there.
    • I did not go to GTR Festival. It's quite a long drive and the car wasn't dialed in yet. I also wanted to see how the racing portion went before going. From what I can tell the classes were not heads up, index, or bracket - just whoever has the quickest ET wins. Never heard of that sort of thing before and maybe some people like it but it's not my cup of tea. I don't suspect I'll go if that is how the racing is done. I did get the car out three times and had issues each time. Some were my error - haven't raced the car in over two years - and others were parts. Had trouble getting the clutch to slip correctly and remembering how it was set up in the Haltech. Broke some drivetrain parts as well that couldn't be fixed in a couple days to get back out. Season definitely didn't end the way I wanted but at least the bearings are still fine! Not a fleck of material in the filter. Really hoping next year is the year I can actually test this car properly. 
    • find it funny everyone claims different fuel chains, do different things with their fuel blah blah blah. We don't have that many fuel terminals in Australia. The fuel tanker trucks drive into the terminal, fill up, and drive directly to the service station and dump out. The majority of fuel you get, is coming out of the same terminals. The variation is actually at the individual service stations and how good their tanks are, as well as how much turn over they actually have. Older fuel stations, that haven't had their tanks replaced are going to end up with the worst fuel. Also a lot of older stations have shit design, and shit maintenance, and end up with more water absorption into the tank. This is when you then get a bad batch of fuel. Other shit things happen, like tanker drivers have a f**k up, and starting to unload the wrong compartment on their truck into the wrong tank. 
    • Yeah go with that one 
    • This one?? In other news: I cannot tell the difference between my red MX5 with the silver grey hard top......... and the Ferrari 599XX EVO, they might as well be twins, well.......apart from the big wang hanging off the back of the Ferrari...🤔🤣, without the wing they are identical
