Ive ran about a tank of lucas through it, its helped but not cured. sometimes it runs great and other times kicks the engine light on and acts funny.
I found the whole spider kit for it, ive got a friend who owns a shop and at least I can get it a little cheaper that way. If its a needed upgrade then ill go ahead and do it to prevent problems in the future. Ive always had fords so im just learning about this one as I go. Would you replace the injectors or the whole assembly if it was your truck? If I go through the trouble of doing it I dont want to do it again anytime soon. and thanks for the info!
