hi guys i have a1996 323 coupe which has a fair few miles on it but it has been well looked after and we all know these engines are good for 300k and more if looked afer properly.
I decided to treat the car to 6 new bosch super 4's and 6 litres of mobil 1 0w 40 fully synthetic oil, a new oil filter and a new air filter. since then it has been irregularly misfiring. it misfires worse when cold and once warm is slightly lumpy on idle. i have checked both front lambda sensors crank position sensor idle control valve air flow meter and throttle position sensor and i have come to the conclusion that they are all working. if anyone can point me in the right direction as to where to look next that would be most helpful.
