Tried an ignition module tonight, no change. Noticed that when I dropped the bonnet that the car stuttered, thought it was alarm based fiddled, no change. Fiddled with AFM wires and got varying reactions depending on which wires I hold and if I earth them or not. Noted some elec tape on the AFM plug wires, peeled it back, looks good enough but something has been done there before. Pulled the airbox out, cleaned the AFM's and their plugs and tried to wrap the wires separately to ensure no earthing, put it all back together, same problem is evident. idle has also at 1200rpm too, this was evident before I did my stuff tonight. If I try to rev above say 2500 it misfires at all temps which suggested coils/plugs (new plugs are arriving tomorrow anyway so they'll go in and I'll inspect each coil individually while I'm there (they're splitfires and the car has 35,000k's so if they're genuine the coils can't be too old but in reality they could be up to ten years old - didn't think they were prone to failure though?) I pulled coil and plug number one and both appeared fine for reference. The loom that the AFM plug runs into looks a little worse for wear in my opinion too.
What's everyone's thoughts? TPS? AFM's? The car is booked in to an autoelec on Thursday but if I can sort it myself and save myself another day of driving the 1.6L Corolla I'd love to =\
