Hello people...

lookin for some advice/help with my focus (2004 ST170)...

Driving to work this morning, Heard what i thought was a stone hitting the underside of the car (somehow dont think it was anymore).... then a short period after the E.M.L came on and i noticed a rattling, like a heatsheild rattle noticeable from inside the car...

i got the car to work, and borrowed a universal code reader, which presented me with the P1518 code... i looked the code up on the net and found P1518 Intake manifold runner control stuck open....

the rattle i now think is the flap in the inlet manifold that breaks up/off ? but im unsure as to how the system works and what the likeley causes and solutions are...

any tips advice most welcome

thanks very much in advance

Rosco
