My Skyline R32 Gts t 1993 RB20DET wont stay on idle. I dont know much about cars but when i start up my car it will start and rev up to around 1200rpm and then the revs will just drop to 0 and the car will just turn off. If i try and start the car up again i have to push on the accelerator to keep the revs up or it will just die, but after i've driven the car for about 10mins the car will stay idle around 900rpm.
If anyone knows why this is happening please help me out because i've taken it too mechanics and all they did was change spark plugs but that did not fix the problem.
