when you first start up the engine it idles ok or it dies .Normally it idles if you try to give it a little gas then it missies like it wont rev but will eventually rev up . the longer it runs the better it gets though .it never completely goes away .when you let out on the clutch and give it gas it is like there is a delay on acceleration.it seems to run great at wide open throttle. I am open to suggestions. I had checked the TPS and it seemed ok and fuel pressure at idle but maybe I missed something
