Try unplugging a coil in turn. (eg. Run engine, see how it sounds/backfires/misses cylinder then turn engine off unplug coil 1 retry to see if sounds same. Then plug that back in then remove coil 2 plug, start and see what it sounds like etc etc) If you have got a coil breaking down, when you run it...
I have got nothing to compare to as when I got the car it already had the lightweight flywheel on but I love the way it is with it fitted and it's my daily and it doesn't make it hard to drive or anything. The previous owner included a box of parts and in it was the original dual mass flywheel. When...
Not sure on this but I presume you havent got a spare key that you can try? Have you looked inside the box where the ECU lives to seen any signs of damage or water etc?
Not sure on this one myself but it would be useful to know, as it is for any parts that are or aren't interchangeable between the IS200/300 and the RS200
It does sound like eletrical gremlins from relays or wiring or that you have got some water in somewhere (on the ECU maybe?) For the fuel gauge though, its got to be worth taking the rear seat out and pump out to check the flaot and change the fuel filter while you are there. i put off changing my f...
Mine has had a solid, lightened flywheel all the time I have had the car and the previous owner fitted it. He told me it was the one off ebay which is this one: http://www.ebay.co.uk/itm/TOYOTA-ALTEZZA-2-0-SXE10-3SGE-LIGHTENED-AND-BALANCED-FLYWHEEL-/361477725705?hash=item5429c05e09:g:19QAAOxy5QtSAhG...
It will vary dependant on age and condition but the most important thing is that it is fairly consistant across all cylinders. If there is more than 10% difference in any of them then something is up. For reference, mine got 158 - 160 - 160 - 165 when I did it last year or so. Some engines get more ...
TBH, I'm not sure on good ones but at least there are a good few over your side of the water - they are very rare to come up for sale over here (although admittedly a few more have changed hands recently)
When I bought mine in November 2014 there were only two on ebay in UK!
