94 Civic Eratic Idle Problem - Have read all posts still no luck!
 

Hi all. This is my first post to the group I hope I'm able to get help.

I have a 94 Honda Civic D16Z6 1.6L V-Tech. It overheated and warped the
head. I replaced all gaskets mill had the head milled flat and pressure
tested. Replace a busted throttle body (it was broken during removal).
And all attached sensors. Removed and check IAC Valve. Engine sounds
good, sounds great actually. No pinging or valve ticks. However the car
idle eratically after being on for only minutes. Pressing on the gas
causes the engine to hold a steady rpm above 1600. The pedal to engine
response is good which makes me think this is not a timing issue. I
have no idea how to check the timing. I have a Chiltons manual but
could find nothing listed. What could cause this other than known
sensor issues TPS, IACV, FITV, no codes to display, the engine light
never comes on. Engine does not overheat. Just a very very eratic idle,
1000 - 1600 rpm. I'm tired of everyone thinking I want to race them at
red lights. Can anyone think of any other known issues?

Help is GREATLY Appreciated!!!!
