One of the members from anouther Fourms told me unplug the EST and see if runs better It did then he told me to redo the timming so far it running better.
Before you go throwing parts at it take the time to check a few things first. Check all of your spark plug wires one-at-a-time with an ohmmeter. They should all read around 25,000 ohms and any zero readings would indicate a damaged carbon core in it. Then verify your ignition timing with the EST wire disconnected. EGR valves seldom stick open so I really doubt yours is. Then connect a pressure gauge to your fuel rail and tape the gauge to your windshield with duct tape. The fuel pressure should be within specifications at all speed ranges and throttle openings.

Amazing! Tbtr usually wants to replace everything, without trouble shooting, just because it is old! Somebody is going to replace him for the same reason.
If this is a new build up, besides the plug wiring, look for vacuum leaks.
you may have shorted wires at rightside bellhousing clamp you have to check everything before you buy parts for everuthing if you have a short new parts wont work also dirty clogged fuel pump filter or filter under car on passengers side may be clogged try the easy stuff first.
Good advice laurence it usually is the easy thing that drives you mad after you have replaced just about everything else
