Ok pretty well hit my issue on the head here. I have cylinder 6 contribution code and injector 6 circuit high I think it was. Trucks extremely doggy throughout rpm range. When I first start it she does not like to idle hardly. Misses badly. Once warm though it idles but no change in miss or power. Icp pressure is good and ficm voltage is good. Would one injector cause my problem? Sorry to hijack anything just similar symptoms here.
