Hi guys, just wonna ask if anyone experience a occasion engine hikup(missing for approx half to one sec) during slow going with between 1.5k-2k rpm, usually happen when u get to a street with lot of speed-hump ,so when u go v.slow over the hump,then accelerate gentlely toward another hump,or sometime when go v.slow at give-away then slowly accelerate,it happen :? ...only does it sometime,not all time.but fast acceleration,no problem at all..also sometime i can hear it happen on "fast idle" after cold start, from outside of the car..
However, my engine is all standard,spoke to my friend(a sport car mechanic),it does exactly the same on his porsche 996 c4 lately, also with individual coil packs, rekon/suspect its the coil-packs(the one goes on top of the plugs) ??
if anyone has come across /fixed these sort of issue,please let me know B4 i run to buy 4xcoil packs,which i believe its not cheap.. lets say if its the coil-packs cause the problem, what make should i buy this time,std or..and how expensive??
Regard danny
