HT Leads when on the way out have a tendency to break down more when hot. Also Coil Pack may be going West.

thanks btmaldon have now orderd her a new coil lets hope her horses get released by that or it time for an st220

Where are you getting the coil pack from. Some after market ones dont communicate properly with the ECU (so I found with our SportKA). It may be worth changing the HT leads anyway as they only have a limited lifespan and as plugs dont get changed so often these days, they dont like bieng pulled about after years of remaining untouched.

thanks guys the coil pack is an ebay item an had plugs an ht leads done last yr when prob first happened but no improvment new coilpackj on way as seems only reasonable explanaion now but will replace all elec components anyway over the time until resolved
