Hi all. So, After much searching on the googleator with no results, I've decided to pose my question here. I have a 2001 accord 2.0l SE VTECH (F20B6 Engine). There's a rattle on cold start-up that gets quieter as the motor heats up. I't only occurs between 2000 and 3000 Rpm. It sounds as if its coming from under the rocker cover but its one of those rattles thats hard to pinpoint! When the engine is warm it gets quieter but doesn't disappear completely. I have also noticed a slight flat spot/miss under acceleration between 2000 and 3000 Rpm also. Does anyone else have this problem? I'm using 10w 30 fully synthetic oil. Have given the car a full service, changed plugs, filters, cleaned egr valve and ports, cleaned throttle body and iacv. Any thoughts or advice would be appreciated.
