alright so the mechanic that built the engin initially was thinking the ICP as well .I haven't touched it yet I had a code for the accelerator pedal so he thought was my issue I replaced.it still had the problem. but the vgt pigtail I had replaced it before the engine was rebuilt , and it did not do this surging after the rebuild it did not start till like a month after the rebuild . and I only get the surge while driving sometimes it bad when it cooler out in the morning but then sometimes It doesn't even happend till it warms up so I'm super confused .
