Hey Guys, I have a 1987 mr2 4age engine fuel injected. When you start up cold, it runs great for 2 minutes. Then the rpms drop to 4hundred . Press the pedel and no change. Turn it off the engine and restart it, the rpms go to 4 thousand easy then back to 4hundred in at split second. If i let it sit and idle for 3 minutes exactly it runs great from then on. If you stop somewhere and the engine cools off completely , you have to start the whole process all over again.I need help.
