Scenic 1.6 bad idle and pick up.

51 plate scenic 1.6 went over some speed humps one morning and car started to stall at every stop. when started the idle is very low and like pulses up and down. We have changed nearly every sensor on car and still the same.

changed all plugs all coils crank sensor idle control valve map sensor and so on. I would appreciate any help or suggestions I have even had it compression tested to check valves etc.



Thanks Chris.
