I recently upgraded to a Walbro 450, 2150cc injectors, New AFPR, JMF Drag Intake, and Taylor 10.4mm wires.
Car runs very lumpy!
At 1st I really thought one cylinder was not firing (Sounds like a subaru). But each cylinder "seems" to be getting fuel, and spark.
All Spark plugs seem to show indication of fuel delivery (slightly wet, and all are getting fouled)
All wires are delivering spark (I can get spark to jump through the wires onto the valve cover)
Coils seem to be firing (although coil on 2-3 seem to be easier to get spark jumping through the wires)
If I pull one wire on any one cylinder the car runs ruff'r. Never does it sound the same if I pull any plug wires off (which would seem to indicate that each cylinder is firing)
Cold Compression check shows 167 across all 4 cyls.
Each Spark plug fouls very quickly and very dirty.
I clean the plugs very clean, and after just 2-3 minuets of the car running they are all equally very black. (picture is attached).
Turning the fuel pump on with ECMlink... Fuel Pressure Regulator is set at 42.6psi
Here's a video of it running

Looking at this it really seems to look and sound like its running on 3-cyl.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Can ya'll look at my log and settings to see if anything is really out of place???
Someone mentioned I may have the injectors wired wrong?
When wiring the connectors on... I was under the impression it did not matter which wire I wired (plus and negative).
What else can I check?
This is becoming very frustrating
..................Any Help would be greatly appreciated!
