will not rev/misfires


Hi guys, my 97 PS is running like arse.. Hopefully you can help. It starts and idles fine, however under load or revving it, it breaks up as you can hear in the video. I have done the following.

1. inspected the fuel filter (which was replaced 300 miles ago) and it was prisitine

2. cleaned out the fuel pressure regulator screen (it was nasty but had no effect)

3. checked fuel pressure (72 psig at idle)

4. unplugged the injector pressure control sensor (still acted the same)

5. no codes.

6. It seemed to occur right when I hooked my cheapo actron scanner to it, which I have since learned doesn't work anyhow.. I was looking for another problem which I have solved.. I dunnno if this is involved or not but it seemd to happen at that time.

7. mm that's about it.. Thanks for any info!
