Message: [QUOTE="genie144, post: 75482, member: 431"] I am having a new issue with the truck that has me a little confused. I finished [URL="http://powerstrokearmy.com/forums/showthread.php?t=2851"]revamping my fuel system [/URL]and had put ~500 trouble free miles on the truck. I then put fuel in my in bed tank and decided to test the valves. I discovered in a hurry that the inlet/outlet for the return line is reversed - not a problem when valve is not closed but big problem when engaged. After fixing that in the gas station parking lot, I drove the truck another ~20 miles without any issues. On the way home it started - foot on the throttle, the truck seems to turn off and right back on instantly. Idiot lights on gauge flash like the truck just started. Aftermarket gauges all flash like they lost power. I lose throttle control when this happens - to regain I just have to take foot off pedal and it is instantly back (resetting the TPS signal?) It seems almost like an electrical surge, bad ground, or short. It will do it 20 times in 30 seconds and then I can drive 5 miles and not have it do it at all. I have checked all of the wiring I messed with, valve cover gasket, all aftermarket wiring under dash. At idle, I have pushed, pulled, etc on it and not been able to replicate. I read the thread below about the OD wires - I will check that next. Just looking for any ideas on this. Sam [/QUOTE]
