I recently chiped my ecu using a Amtel EPROM and all the other parts listed on the how to that I found. The problem is that the car will run great for a while and than the car starts to sputter and run like it is only on 2 cylinders. If i let the throttle of the idle will go down and it will just stall. If I plug my stock ECU in it runs fine. I cant check codes caus it goes full limp (solid light). Does anyone know what is causing this??
