I have had my car plugged into the diagnostic machine because it has a spluttering problem when moving and on idle. Can someone help me with the following codes?

P0322-16706 = Ign./distributor eng.speed inp.circ no signal.

P1103-17511 = o2 sensor heating circ.,bank1-sensor1 output too low.

P1425-17833 = tank vent.valve short to ground.

P1527-17935 = Intake camshaft contr.circ.,bank1 short to ground.

The bottom one is the most important one i think.

Thanks

If its playing up on idle & when driving my bet is the speed sensor or possibly a lambda(o2)....other faults will be brought up if something goes wrong, best bet is to take this info to trained mechanic...they will charge you to plug it in & run a diagnostic otherwise
