Basically the situation is this. My Rx-8 was equipped with the Zex wet shot system. Most of you are probably familiar with how it works. Its solenoid operated during full throttle situations.
One day after using nitrous, the solenoid stayed stuck in the open position, continually spraying nitrous without my control. I tried to pull the car over as fast as I could to shut it down, but my upper intake manifold exploded and the only thing I could do was call a tow truck.
I replaced the UIM and all the other broken plastic bits. I even had to replace the throttle body because the butterfly valve had been bent during the explosion.
The car starts right up, but holds idle very very poorly. The car is AT, and will even stall when putting into drive. Once you get driving, it seems to behave normally... there is not a noticeable loss of power but the motor begins to make a "growling" noise around 5krpm+
I am going to replace the plugs today and check the oil for shavings. I understand there is a good chance the engine is screwed... but nevertheless I want to weed out all the simple things first.
Does anybody have any suggestions to what the poor idle, and growling noise could be? I know that loss of compression symptoms include hard starts and marbles in a coffee can, but my rx8's issues seem to be different.
