Just replaced the timing belt and pulleys. The car is in time, on a cold start it idles fine but as it warms up the idle gets rough. Code coming up was P0453. The check engine light is now off but the car still won't run right. It has an intermittent miss as you rev the engine up. Any ideas on what to check? Sparks tested on all four cylinders and they are fine.
