Hi all,

This is the second timing belt change on my 96 Civic. This time it went
much smoother than it was 100k miles ago, BUT...

When I went to start the car, it went straight up to 4000rpm, then continued
onto 4500rpm at a slightly slower rate. It remained there until I shut off
the engine (about 15 sec later), since I knew it was not supposed to do
that.

I checked the obvious like a wrench got struck on the throttle arm or a
kinked throttle cable. But none of that.

I did a preliminary Google search and it seems to point toward the idle air
speed control or a vacuum leak. I don't see any disconnected hoses. Is
there an area I should concentrate on? Could the IAC be the cause?

I have the factory service manuel, but I need to know where else to look.

Thanks in advance
