Ive been working on this problem for months now.. since the weather is getting colder.. the apparently the signal for my cluster gets worse.. in the morning when the car is cold.. the cluster is stuck.. for example.. the car will be on and idling but the pin is still at 0... when i give it a rev.. to like 3 grand.. the pin jumps to 3 grand then gets stuck there.. as a drive to school.. the pin jumps around not crazy.. basically whatever rpm.. i go to.. it goes up too.. but not really acurately .. but as the car warms up.. the tach seems to correct itself.. i have a shiftlight.. and i recently.. did all the connections over again.. i checked all wireing.. i just cant fix it.. its really frustrating.. i even asked some techs at acura.. who are friends of mine.. and they cant figure it out.. **** like this is really pissing me off. and it cant be the cluster.. cuz once the tach corrects itself.. pretty acurate for the rest of the day.. unless it turn my car off for a long period of time..
PLEASE HELP!!!!!!!!
