    Where are you located Heavy D I have questions regarding my truck but I think I'd rather just bring it too you.

    You have more answers than anyone else I've' spoken with. My problem is intermittent and of course when it's in the shop it doesn't duplicate the problem.

    Low power, low speed it may not do it for days at a time. When it does I'll flash the key off and back on real quick that seems to clear up the problem which allows me to drive it somewhere safe to wait for it to begin to drive properly.

    I would check it for codes and go from there. I would also road test it and record a 0-60 snapshot to see how it is performing. Intermittent problems are tough. This is when the guessing game starts.

    Purchased a 2010 prostar I spent a lot to get it right. I just replaced crankcase breather. Now I am losing power. The crazy thing is it's a small amount of power. The only problem I have is on the up and up hills. The warn engine is on but it goes away when I turn key on and off. For awhile the power is back on but if I push in pedal engine warn is back on. Hopefully someone can help thanks

    You need to get it scanned to see what fault it is logging.
