  15. LOSS OF POWER, INTERMITTENT ROUGH IDLE

    6.0L Problems Forum
    At first I thought it was a bad injector, (no smoke of ANY sort) so I threw in some injector cleaner/octane boost. The symptoms went away, about 50% better. Still a loss of power and at about 70km there is kind of engine surging. If I take my foot off the throttle and step on it if goes away...
