well, ive replaced all of that several times over and it has never helped.
just replaced the coil packs yesterday and guess what.............................................. .................................................. .....................................still does it.
im at a loss. may have a lead though. was reading about what a bad throttle position sensor will do and it sounds similar. so i unplugged the TPS and car drove exactly the same which leads me to believe that could be the problem. luckily i have an extra one

well, i replaced the TPS and lowered the fuel pressure slightly and it now only does it from 3700-4200 RPM at full throttle. it seems to do it less and less the lower my fuel pressure is, so now im starting to think its fuel related (on my vehicle anyway). i will put the stock fuel rail and FPR back on this week to see if it changes anything.

and now not so much....
I've ran 2 bottles of Techron cleaner through there... and it's still doing it...
It seems it would clear up for a bit but now it's worse - happens when the car runs for long periods of time as well.
It will stat to shake pretty rough and not move anywhere - still sounds like a misfire to me. I need to replace all the coil packs and possibly the TPS?
ANy other ideas?
Thanks
