sounds like it could be fuel cut how long have you had those mods on for

[paul mc]

they have been on the car since i bought it about 10 months ago .

when did you do a service lasts dizzy plugs etc etc? if you keep it off boost does it drive ok if so i would imagine it would be ignition related

actually just changed oil, oil filter and plugs about 3weeks ago to bosch super 4s but was misfiring/coughing so changed them back to the hks ones that were in and was running fine until now ??

[paul mc]

has anybody got any ideas ???

check the plug gaps, and also for water contamiation in the dizzy cap, i found this with condesation and jetting the engine bay of, if you have accessiblity to a air blower, blow down all the plug holes inside the dizzy and spay some wd down the coils, after that check that nothing has come a drift i.e. leads or wiring to air flow meters and map sensors

let us know how you get on

the lead from the dizzy cap to connector at the back of engine bay was split thanks for your help.
