I have a 1998 honda civic ex auto trans. 130k miles. When push on the gas peddle the rpms go up very slowly. It only goes to 3k rpms then surges back down to almost 0 rpms. When I put it into drive it drives but very slowly and I have to push the gas peddle to the floor board. In reverse I have to use my foot like Fred Flintstone and give it a little help. My check engine light is on with P505. I have checked for vacuum leaks (none). I checked for air inside coolant (none). I did replace the PCV valve. I put my finger over the lower port inside the throttle body, the car dies. I have checked for leaks on my manifold gasket (none). I have taken off my iac valve and cleaned it. I verified the TPS with a volt meter (it was good).

Before I spend $200.00 for a new IACV, is there anything else it could be??

I'm new here and in the wrong thread ...
