I've noticed a wierd problem that some of my friends have with there Supras aswell, when it's damp outside the car runs shitty as hell, it can be something like this:
1. Start the car up, no problem at first, idles well...
2. Give it some throttle and bam it hesitates and stalls...
3. Next startup attempt and the car might stall again directly...
4. Start it up again and this time give it some throttle, idles very bad, if I let go of the throttle it stalls 100% or will be down to 200rpms maximum...
5. I drive the car for a while and it seem fine but as fast as I decelerate the check engine light comes on and as fast as I push the accelerator the car hesitates but then drives ok again and the check engine light will come off...
6. After some driving there will be no problem at all and I can stop and start the car as usual with no problem, also resetting the ECU sometimes fixes the problem right away but I think this is realy accidental only...
Now something I've noticed is that my Apexi TT get's realy fucked up readings on it's A/F sucky as display, seem that i'm running pig rich as soon as the check engine light comes on...
Now my own personal guess is that the AFM gets screwed up when it's damp outside, any thoughts about this?..
