hi all.
got this in at the moment,customer complaining of "judder whist driving".management light on.
codeS read.
1.P2050 misfiring,damages twc see currently valid strip P0300.

2.P2052 misfiring of cylinder 5,damages twc,see currently valid strip P0305.

3.P2055 misfiring of cylinder 6,damages twc,see currently valid strip P0306.

have cleared codes,road tested with live data,
starts & drives lovely,after a few miles,light throttle,slight hesistation/holding back,drive a bit harder,slight misfire,drive again,ok for a few miles,then this hesitation reappears,all live data ok,& management light not coming on?
fitted new spark plugs a few weeks ago ,genuine plugs.
i think it might be the m.a.p sensor,but at £196 i'm a bit reluctant to fit one & not fix it.
any advise would be nice.
