I can adjust your tps if needed (shouldn't need to unless you've played with it though!)

Be cautious not to dismiss your AFM. While mine is a different design to yours, i believe my AFM to be dieing intermittently at the moment and the idle is fine. The driveability is fine - It's just when on full power up top that it jerks badly.

Hope you get it fixed..h

think the problem solved by itself after taking out the negative terminal on the battery....

ross came wif his expensive obd2 scanner and tested for cels... to no avail. everything was good, afm, o2 senor, injectors etc all did well.

last resort, reset the ecu for 15mins in an old fashion way... unplug the -ve terminal and wait and wait and wait..

once the baby was fired up, it seemed to run fine, tap the throttle and no dramas. turned on the aircon and the idle went slightly up in response. gosh wad a miracle.

took it out for a test drive and gave it good boost, rpm doesn't go all the way down to the brink of stalling.

Solution: i sprayed the shiet out of the idle control valve sensor with the upper engine cleaner and had it dried and wiped off the excess. put it back on and resetted the ecu via the MRT way (2 connectors below steering column). this did not essentially reset everything.
the only way to do so was to disconnect the battery and deprive all things of power. this was the old-fashion reset which made the ecu learn that the idle control valve is very clean now and not send the intermittent signal as before when it was filled with blowby oils, gums and carbon.

guess this issue is sorted out now.. for now. cant run my car w/o the "read" diagnostic cable connected. this is seriously 1 hell of an ecu problem... pls let the holidays end soon so i can tune my car wif my power fc and a z32 afm.. PLS PLS PLS
