SCT live link problem/ICP
i useually have my own answers but this is throwing me.
1st i searched the site to find the answer and no luck so
i'll reach out to the wealth of information traped in your heads
right between the left and right brains.
I've been having a dreadfull surge at 625 rpm on an 03 6.0l,not enouf to cause the vehicle to move but in drive and on the break it does it.
so i downloaded the SCT live link ran the data and found the ICP duty cycle was
gaining about .3v every 5 seconds on the dot. wihich was causing the injector rail pressure to rise and the surge to happen,NOW with the same
SCT SF3 programmer it does NOT get and DTC codes or find anything electricaly wrong.The sensor is 4 months old,and there is no signs of any internal leaks.
But this surge still remains.
what would cause the ICP to fluxuate like that and the duration is for about .5 seconds then voltage tapers back to constant reference,
thanx in advance
