Because:
- The S4 RX-7 computer has a glitch which sometimes causes it to flood if the engine does not run very long. For example, if you start the engine, drive the car a few hundred feet and then shut off the engine, then it will probably flood when you try to start the engine again.
- Leaky fuel injectors or a worn engine can also cause flooding.

You can send your injectors out for cleaning for not too much money. Be sure to install them with new o-rings.

You can pull the green EGI INJ fuse rather than disconnecting the fuel pump.

Only if the engine has a lot of hot spots due to severe carbon buildup or other problems that cause knocking with regular unleaded, or if you are running a higher boost level than the factory setting. Otherwise, higher octane is a complete waste of money.

 

So can you remove your airpump if you have an S4 with headers and I think somebody said without the cat it could. With a straight pipe and airbox and no airpump would that be a cause for a couple ponies?

 

12 psi . ill keep running 93. thx

 

well my teacher says that it can be a sensor thats behinf the alternator it a green sensor and he says that it the coolant sensor that tell the computer if the car is hot or not. but i think it can be the thing that controls the idle . the BAC i think its called . but im really not sure. i also have a problem that when i turn on the a/c the rpms drop as if the engine wanted to shut off. Ohh and one more question how do i test that my valve thing that opens up the 5th and 6th ports is working. i know im suppose to put grease on them but i want to know if they can open when the car is in neutral and i were to rev it up to 4500. because i do that and i dont see them move.

 

ohh i dont have the fuse cover so which one is the egi fuse looking at it from the front. just give me a number. like saying the 5th from the right as an example.
