Does it do it on hot starts or cold starts or both? If its cold starts only, I'd suspect ignition components. Drench them with water and note any difference and drench them when the engine is warm, too. Wetting the ignition components should have zero effect on how it runs. If it does, there

Of course, we all love this arm chair quarterbacking. Personally, I'm glad for all the tidbits. My vote is the fuel filter. Seems to flow crappy until you force the pressure up on the pump by cracking open the throttle. Of course, if it goes away when it warms up or you drive it a block or two,
