172 CUP ISSUES

[ADS_V6]

Hi after some help got my 172 cup problems sorted it was starting bad from hot and cold,it has had the following

New Battery,leads,ngk plugs oil and filter,new crank sensor and loom and battery and coolant temp sensor now from cold theres an annoying misfire from 1200 15oo rpm when cold it was there before i was hoping new parts would sort it also when engine is warm the car seems a bit hesistant ie not as quick as i think it should be when driving 60 and flooring it seems a bit like hesitant to fly,any help please thanks al

Compression test then timing check should flag up something. Swap the coil pack for a known one before but I can't see that being the problem.
