jonn Posted March 28, 2005 Share Posted March 28, 2005 Might be the crank angle sensor, my vl did the same thing and that's what it was. Link to comment https://www.sau.com.au/forums/topic/68609-urgent-car-dying/#findComment-1271351 Share on other sites More sharing options...
DLuded Posted March 28, 2005 Share Posted March 28, 2005 have u tried the air flow meter the AFM always screw up i have a 89 gtst and my car would randomly run like shite. it would drive smoothly then all of a sudden, while my foot was on the accelerator, it would seem as if i had taken my foot off and then kick back in. it would jerk back and forth until i took my foot off the accelerator. sometimes i would pull over to the side of the ride and it would idle really high around 2000rpms then act as if nothing had happened i purchased a 2nd hand air flow meter for $70 and it did the job Link to comment https://www.sau.com.au/forums/topic/68609-urgent-car-dying/#findComment-1271386 Share on other sites More sharing options...
seeyagtr Posted March 28, 2005 Share Posted March 28, 2005 It might also be a good idea to check the retainer bolt on the ECU. Link to comment https://www.sau.com.au/forums/topic/68609-urgent-car-dying/#findComment-1271392 Share on other sites More sharing options...
raz0r$harP.UK Posted March 28, 2005 Author Share Posted March 28, 2005 thanks for the reply guys.... afm has been previuosly checked and was fine I'm guessing retainer bolt is to make sure the ECU is sitting ok and wired right?? It's been relocated to glovebox. cos my ecu is in the glovebox has a piggyback ECU attached i put the car into consult mode and ecu flashed code 43 which is for TPS. Any suggestions as to what is causing this? AHHHHHHHH Link to comment https://www.sau.com.au/forums/topic/68609-urgent-car-dying/#findComment-1271434 Share on other sites More sharing options...
seeyagtr Posted March 28, 2005 Share Posted March 28, 2005 I had the problem were the plug came lose on the ECU and every time I hit a bump the engine cut out. The retainer bolt on the ecu plug was loose. I do not know if this is what is going on with yours. It does sound electrical it could be anything on the inigtion side. Do you have an after market alarm or checked through the wiring harness for any damage.?

raz0r$harP.UK Posted March 28, 2005 Author Share Posted March 28, 2005 haha oops forgot to add problem happened last week mechanic checked tps and said it was fine Link to comment https://www.sau.com.au/forums/topic/68609-urgent-car-dying/#findComment-1271553 Share on other sites More sharing options...
siksII Posted March 28, 2005 Share Posted March 28, 2005 the tps may be an intermittent problem, so although your mechanic says it is fine, and it probably was when he saw it, at other times is may not be working and it might be causing your problem, i know my tps acts that way, sometimes it will be fine, and then all of a sudden while driving the tps voltage will drop to 0.01-0.09v (normally minimum .38, i can see the voltage on the pfc hc) and the car will turn off if i back off. so try and change the tps, since you know the ecu is picking up a problem with it.

bretto Posted March 28, 2005 Share Posted March 28, 2005 what you just described is exactly what my r32 did once, mine was the airflow meter. had two different auto electricians look at it and the first said the afm was fine and couldnt find the problem but the second found the problem. maybe see if someone has a spare afm you can borrow to see how it drives then?

raz0r$harP.UK Posted March 29, 2005 Author Share Posted March 29, 2005 hey yea im going to change the tps quick question is the r33 tps the same as the r32 tps talking both manual gtsts ? also had a quick look today is it hard to take off ?

Cubes Posted March 29, 2005 Share Posted March 29, 2005 I had a similiar issue. It turned out to be the wire going to the afm had a faulty connection. I installed an SAFC previously and then removed it. The Plug that I used to connect the AFM wire together (as per the SAFC manual) was causing a dodgy connection. I removed it, soldered the wire back together and its 100%. I discovered the problem when I hooked up a powerfc. The AFM signal was completely dropping out. I don't believe its the TPS. How was the AFM checked out? I don't believe it was checked properly.

R31Nismoid Posted March 29, 2005 Share Posted March 29, 2005 As joel said... common problem there. With wiring. It causes many problems, and also causes the ECU to give out false information does the car totally die? If it doesnt totally die, id say against the CAS... if it was dying and then wouldnt start for around 10mins... then thats tell-tale of a stuffed CAS. Get someone elses AFM if you can. and work back along wirs Link to comment https://www.sau.com.au/forums/topic/68609-urgent-car-dying/#findComment-1273329 Share on other sites More sharing options...
siksII Posted March 29, 2005 Share Posted March 29, 2005 hey yea im going to change the tps quick question is the r33 tps the same as the r32 tps talking both manual gtsts ? also had a quick look today is it hard to take off ? easy to take off on r33s anyway, im sure it would be easy on r32s as well. i dont know if they are the same, best to call nissan they could probably tell you what other models use the same tps. try swapping with a friend first to make sure that it is really the problem, because it could be something else, or maybe just contributing to a larger problem Link to comment https://www.sau.com.au/forums/topic/68609-urgent-car-dying/#findComment-1273334 Share on other sites More sharing options...
raz0r$harP.UK Posted March 29, 2005 Author Share Posted March 29, 2005 well what happens ill be driving normally then suddenly its like it just cuts out ...the engine is still runiing and car is still on ... so it hasnt stalled but the revs drop slowly the fuel pump cant b heard although when i floor the accelrator i notice that even though i am not getting and power or the revs are rasing the boost controller still shows the changing vacuum but never builds boost obviuosly it eventually slows really fast then dies and then starting it takes a few times but usually repeats ill have to check the afm wiring then (hada look at the ecu harness but didnt follow wiring will do that though) but yea my bro has a r33 so ill change tps (just as a test ) try drive closeby then go over afm wiring once again thanks for all the input guys Link to comment https://www.sau.com.au/forums/topic/68609-urgent-car-dying/#findComment-1273400 Share on other sites More sharing options...
