Hi everyone. I just bought a used 2003 F250 Power stroke 6.0, and I love it, drives nice. However, I have notice a very slight hic-up, or vacuum stall, skip in possible fuel. Kinda a popping sound some time 4 or 6 in a row, last less then .05 secs each. At 1st I assumed it was a Cruise control vacuum issue, but ir happens when its off as well,. Seems to happen only at high speeds, + 50 mphs. Currently the Check Eng Lite is Off. Ive read that the 7.3 has this issue and its a cps, but the 6.0 typically does not have the same issue with cps.

Thanks in advance,

Steel
