Message: [QUOTE="Powerstroke Racer, post: 761575, member: 13"] [COLOR="Yellow"][/COLOR] You stated the above in yellow as FACT then in red you show that your statement was in fact limited by your understanding or lack of understanding how an internal combustion engine operates. If the CPS signal was bad and did in fact shut down then more than likely nothing would happen but is was an intermittent problem. What if the signal got interrupted half way through the injection event of a particular cylinder but not enough to fire the combustion event in that cylinder, what happens to the small amount of fuel that is still in the bowl? The air is still there as boost did not stop just for that cylinder, piston comes back up with no new fuel being injected and you have compression and full boost, you end up with a very lean condition which can wreak havoc on cylinder pressure. Do you know how many times per second that piston will come up on a compression stroke at 3000 rpms??? [/QUOTE]
