performance loss???????

[BTEC]

ya my exhaust leak is thowing a code, for a knock sensor.....could that be doing it. it does kinda seam that if the check eng. light is off car runs better???

i think if u have a knock sensor code then ur car automatically takes timing out causing a loss in power.

I would fix the check engine light first then i would do a tune up on it and see how it runs then.
