hi~
My 95 m3 was running horribly (power loss, hesitation, terrible throttle response) and i did the stomp test to get the code and it told me high low oxygen sensor range limit. Changed the o2 sensor and it runs somewhat better but still horrible....it worsens the longer i have be driving.....when i get off the gas the exhaust is very rumbly and occasionaly it will back fire. and i still get intermitten check engine lights but if i floor it the light will go away. the motor wont let me cruise at a steady RPM for too long... i really need some help.... i dont want to just start through money at random things hoping to fix it. I am thinking right now since its running on the rich side maybe a leaky injector....? i am going to do the clicking/screwdriver test today. i replaced the plugs recently and they were extremely worn but they all looked the same and i believe it was just from not being changed sooner......thankx
