1996 ex idling issues

[Geovair66]

Hello all new here, I have a 1996 ex that won't stay running till it's fairly warm. The eccelerator pedal has to be held in to keep it running, it idles around 450 or so when warm.. I am getting codes p1508 and p 0325. When the throttle is held the tach bounces but get smoother as the engine warms up. At high rpms it smooths out. Any help would be appreciated

I believe your knock sensor and IACV use the same plug type, first make sure those aren't switched around.

Assuming that's good, clean your IACV, and test the knock sensor. Replace if bad.
