It's very difficult to help without OBDII codes, could be an investment you should consider for around £50.00.

Only thing I can suggest is recheck your recent plug change work including the coils for damage and wiring to them.

Just finished taking them back out checked them all making sure there fitted properly retightened them then I removed each coil plug lead and started car on each, car died so coils are all working cheched for breaks in cable or fittings on the coils and they all seem good just wondering if its a throttle body sensor or the throttle body needs cleaning still don't see why that would affect the running
