I meant unplug the PC3 to see if it runs better.

It's runs after finding out my fuel pump was low on pressure I also found my cams are off degree possibly ?

Heres a suggestion...instead of guessing at it or executing a process of elimination?...why dont you just jump the diagnostics port and see if it codes out?
