So besides my brakes going out yesterday I was testing my tps and I noticed when the key was in the on position and when i open the throttle i noticed a buzzing noise coming from the transmission does anyone know of this is normal or something wrong?

So checked the coil today it's working as it should, also cleaned maf still running rough. I guess the next step is to see if its jumped time I will get back results soon

Okay so here is what is going on. I bought a 98 legacy L wagon. It has the 2.2, I bought this car for work so I'm not putting alot of miles in my truck. When I bought it it had some issues. Slow acceleration falling on its face when you had the gas floored. I changed everything I could thin igupdate bought brand new cats and installed them with new gaskets and o2 sensors car is still falling on its face when trying to accelerate. So what has been done, new map sensor, new knock sensor new catalytic converters and o2 sensors new plugs and wires new tps, also I now have a blinking cel. If anyone has any idea what's going on please let me know
