I brought a 1991 honda accord with a blown head gasket. I replaced the head gasket and now have two unique problems. First, I let the engine warm up to a nice idle. Till that point, it sounds good even when hitting the accelerator. The problem is that once it warms up, you hit the gas a couple of times and it just dies like someone has turned the key. The second problem is that the moment you turn the key, it starts pumping fuel into the cylinders thru the injectors instead of just pressurizing the line. In other words the injectors seem to be on when the key is turned even though the engine is not running. Any help would be appreciated. New to hondas and I want to thank you in advance for any help you might be able to give.
