I have a number of issues with the old girl, the latest of which is GEARBOX FAULT, possibly related to a missfire but maybe battery/alternator (yeah I've done the electrical sticky). I've changed battery leads as they were causing a bit of a Volts drop (750mV), cleaned grounds, and I know I have a diode away in the alternator. It's charging ok, but has AC ripple so a new one arrives next week.
I mistakenly did a write of settings to the GEMS from the Nanocom before I took note of the adaptive air-flow rate, but I don't think this is causing my slight engine miss. I've set the AMFR to 3.75 for now as I found someone else that had that somewhere on the interwebs - happy to take advice in lieu of a CO meter check as to what others have as their Air flow rate. My 95 is a cat free model.
I have changed plugs, filter, got new leads in the post with the alternator and will take off the coil pack and have a good look at that tomorrow. I've cleaned the throttle body, IACV, TPS, MASF, (there was a lot of crap in the plenum) and reset adaptive settings. It's idling nice now but has still has a slight consistent miss as though its an HT lead. I have fully charged the battery. I may also have a slight crack in an exhaust manifold but can't hear a squeak, or feel anything with the viscous fan running.
The problem is this (with a fully charged battery and 14.2v alternator charging): ignition on, no gearbox fault, can press sport and get the light and dash message. start car, car idles, a few seconds later "GEARBOX FAULT".
The nanocom only lists a fault for the Gearbox ECU - ENGINE TORQUE FAULT. Looking at the reference manuals it looks like the miss may be causing the ECU to send the gearbox an under torque signal. Is there any more info on this fault from the Nanocom such as a P code - the reference manual has a few guides, but the code is in english text only.
