I have a 2002 wrx, at 30k miles the engine management light came on and the car needed a new neutral switch, at 61k the engine management light came on again and the car needed a knock sensor, after about 100 miles the engine light again flashed a bit, cleared and has been ok. today at 62350k miles the engine management light has yet come on again and stayed solid yellow, is it common for me to have experienced 4 lots of this engine management light problem.?

 

4 times in 32000miles its not the end ov the world, bet theres a few had worse
