Since the maintenance was known but old, i proceeded to change radiator, brakes and pads, all fluids, plugs etc.
Today we took it for a drive and after a couple of 8000rpms shifts the engine dies down and now revs only to 5500rpms.
I am looking for this forum's help and to tap into your knowledge to see if you can help (aside from saying "get an Emerald" )
- Speed sensor was replaced - no effect
crankshaft sensor was replaced - no effect
wires, relais and fuses behind the seats have been checked - nothing wrong
the diagnosis tool says "speed sensor error" but after trying with 3 different ones we all had the same result: 8000rpms for a couple of gears and then boooooooo limp mode.
Do you think the ECU is faulty and if I try with another 170hp one I may solve it?
