Hi as the title says i put Vpower fuel in after i put my 4-2-1 manifold on it only has 1 lamba sensor n i though that was the reason for the light, looked in the b fiat book and it says that its poor injecotrs or not working injectors that makes the light come on so it wont be my lamabsensor cause thats emintions my mom said it happend to the L200 abit of gunk went into the injector but evenutally burned off and the light went out, could any one tell me if this is a simple wait n it will go or a serious problem? oh also blowin out afiar bit of smoke (think thats the vpower doing its magic) just need some reasurance, oh and the light wasnt on before i put the vpower fuel in....
