I have a 91 civic dx sedan with a 97 LS engine jdm type r tranny. Running a obd1 pr4. After doing some reasearch and getting nowhere I decided to come here. After I rev the engine past 6k rpms the engine shuts off,no check engine light at all. This happends while driving or at a dead stop. I have changed fuel filter, plugs, cleaned the whole throttle body, bought the fast idle control valave and the iac new from honda. And still nothing. Car drives fine but as soon as I floor it it shuts off. Any help is greatly appreciated

 

Anyone?
