Wagon has got worse with misfires. Car is very rough at idle, but smooths out as soon as I am on the gas.
I did some logging with Tactrix cable and saw at idle cyl 2 misfire/roughness counts just kept going up, all other cyl at 0. But as soon as I hold revs at about 1500rpms or higher 0 misfires even on cyl 2.
The car has started making ticking/rattling sound from the engine at idle as well, but goes away with the revs like misfires.
Any idea what it could be? i tried swapping injectors with a used set of injectors from STI also put in new coil pack but nothing fixed it. also replaced both oil control valves, 1 was bad for sure. Could it be burnt valve? or intake manifold O ring going to cyl 2?
