Have you checked: 1) Your engine mounts, particularly the one under the crankshaft 2) Your swaybar end lings will cause that noise 3) Your sub-frame mounts (one of mine had separated from the center portion). This one had me replace the whole front end parts to find 4) Your swaybar mounts have not s...

see if you can play this...it was an MOV file. I converted to MP4 . Are you able to spin it 360?

Ok so I have eliminated the fuel pump--- Not necessarily. If you're not monitoring FP while driving, you really haven't ruled it out. It could idle for hours and not skip a beat. It's a PITA, but you need to see what it does when the engine acts up. It was also mentioned to investigate the electron...
