Please fill out the following to ask a question. Fors Focus 2003 164 k 2.0 Car surges a little when driving When at light it doesnt want to idle. Almost stalls. I adjusted the idle to 800 rpmin gear, 900 rpm in park,to keep it running. When i notch the idle screw up, just a bit, the engine races at close to 4000 rpm. So setting it is tricky. Do i have a leak somewhere?? Help!
