hey guys i recently put a NF wiring loom and dash into my NC, changed over ecu engine bay loom etc.

since doing it, the car feels like it missfires on low throttle.

i started to look at other v8s and compare vac lines etc etc. i found that the two hoses on the EGR spacer went no were and the two holes on the back of the block we linked together, i guess to skip the EGR spacer. i bought new hoses and hocked them up as they should be and then found that the TB gasket had a split and it leaded so fixing that now.

there are 3 vac lines on the back of the intake 1 goes to the brake booster 1 goes to the fuel reg and the other one goes no were?

also the EGR has no vac line on it at all.

Can anyone tell me

A. were does the EGR vac line go
B. why would someone bypass the egr spacer with the coolant
c. the three lines on the back of the plenum were are they suposed to go?

any help would be great

Egr vac line goes to a solenoid in the passenger side guard. Egr coolant lines get looped together because its possible for the egr to corrode internally and dump coolant into the engine, hydraulicing it. I've heard of it happening a few times. This prevents it.

The other vac line is charcoal cannister?
