I'm having this stalling issue that's been going on for a while where the car would cut off when no pressure was applied to the accelerator or the car was at a stop. I took it to Nissan and they determined that my ECU was bad. I bought an ECU from a salvage yard and swapped it. The car was working fine for a while but all of a sudden while i was at a stop sign it cut off. I tried to start it back but wouldn't start until i gave it a little gas and then it was trying to stall again. I feel like it's pulling while i'm driving and when at a stop and not shutting down it feels like it's struggling to maintain 500 rpm's. I feel a vibration on the pedal for a little while the rpm's drop a little then it would fix itself and stop vibrating while the rpm's raise a little again.

 

yea, i think i have that same problem. I got to school at 7:30 am. Get out at 2:35 pm. When i start my car, it just stall out for no reason. I thought it was too hot or something. So i took it to the mechanic, they said i might need a Tune Up. You think thats the problem?

 

i don't think it would just be a tune up thats causing that but its always good to have if the car needs it, hopefully i'll find out today what the problem with mine is

As I said before, the two causes are iacv and lock-up tourqe convertor. And on your car, it is more than likely a lock-up tourqe convertor problem. carefully inspect the wires to your speed sensor, you got that code from your tcm and never dealt with it, well that can cause your symptoms!! You also failed to mention if you have yet to check your fluid level, nevermind replace it. if no problems found, replace your speed sensor.

 

the speed sensor circuit has been repaired and the fluid replaced, but now nissan is telling me that this second ECU that i bought is bad and they're still charging me for reprogramming it

 

I had the same exact problem when 2 of my oxygen sensors went. Whenever I was at a red light it would stall unless i kept giving it gas.

 

Stalling Problem has been fixed, I got another ECU from another scrap yard and took it back to Nissan, they reprogrammed and installed the other ECU and although they're charging me an arm and a leg the problem has been fixed. It seems that the A/C evaporator was clogged and caused water to leak onto my ECU causing it to malfunction. The clog has been fixed as well.

 

Reprogramming it? Consult-II has no function to reprogram an A32 ECU. I know, I've played with every function in it.

 

well i guess it was another one of their schemes to rip me off
