low rev misfires
hi, can anyone help me? ive got a porsche boxster 986, and lately i started having misfires in the engine only in idle. when accelarater is pressed slightly, the misfires disappear, but on idle the engine will sometimes also die. i have the engine check bulb on and sometimes it blinks. ive been to a porsche garage and they are finding it hard locating the problem. they changed the lambda sensors, checked ignition coils, but to no avail. the problem is that the engine is only operating on 3 cylinders in idle position, but when in motion all 6 will fire up. the annoying thing is engine dying in traffic!! any suggestions?
