Have not posted in a while but I a need some help on this one.
My truck has been hiccuping in the morning or after it sits for a while.
I will fire it up in the morning, pull out of my driveway all fine and dandy but as soon as I start to get up to about 20 mph and accelerate easily , the truck will hiccup. It feels almost like the ignition it being shut-off and then turned back on, all within 1 second.
I did notice that my pump bolts had gone loose and the TDCO was at 0.00 so I moved the pump back to my original marks and was able to get the timing back to -2.2 TDCO.
But, the surging/hiccuping is still there.
I have about 240K miles and still running 30 psi of boost....
Any thoughts?
