hi, no haven't tried to drive with the diag tool plugged in, only stationary, although the tps fault seems to have cleared and the app fault stayed up. after clearing that fault I started the car and it idled fine down to 700rpm, rev'd the engine a coulpe of times and it went into limp mode again and the app fault came back up again. reset the etcs-i again and started the car and it idled fine again, then the revs climbed to 1100 rpm and sat there. I revd it a couple of times and although it didn't go into limp mode, the revs stayed at 1100. I will be taking it out hopefully sunday once I refit my calipers back on so I cn try it then.
