Hello All

Hello everyone. New member here. If this belongs in a more specific thread, please feel free to let me know. So here's the short and skinny. 2003 F250 6.0l. 200,000. What began as an intermittent issue has become a constant issue. Cranking is good. Idle is fantastic. But when accelerating beyond 1500 rpm, the rpm become erratic, bouncing from 650 up to whatever rpm I'm asking it to make. I have a video of the issue but cannot post here. I can send to individuals if anyone has experienced this issue. No codes at all (checked with 3 different readers).

Try running with the ICP sensor unplugged.

Here's a short clip of the "surging" (the best description I have).

Welcome here to FTE. Bismic is one of the most knowledgeable members here. I advise you to try his suggestion and remove the connector from the ICP sensor for a test drive.
