I,ve got a 99 Astra 1.6 8v and I,ve just replaced the EGR valve,idle control unit and new s/plugs and it generally drives better.i.e less engine braking than before,therefor smoother take up when re-accelerating.
Problem is it still doesn,t like starting up smoothly.most times it fires and idles too slow for a few seconds then picks up,other times it will stall and when restarting goes to a fast idle then falls back as it should..
Any one got any ideas please..
PS. I unplugged the ECU for 10mins today to clear any unwanted data/fault codes
