Need help with hesitation and rough idle - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

Ok ever since i got this car (89 240sx se manual) when it has been sitting for a few hours, and you start it, it has a very rough idle, I changed plugs and it made it somewhat worse but it is fine after a minute or so. Also I have a hesitation at partial throttle when it is cold, but after a minute or so of driving it is fine. The last problem I have is my speedometer, It works sometimes right away when you start driving but then it stops, until you drive it for around 30 min then it will start again, I have had the gauge cluster out twice to look for bad connection but everything seems fine. I have searched for answers for all these questions but i cant find any problems exactly like these.
