I have a 94 gsr wiht a to4e turbo and the boost is set at about 10-11psi.
My fule system Iam runing the intank pump pluse and inline pump and fmu.
The timing is stock with the msd set at about .6deg per pound of boost.
Well heres the problem iI pulled my plugs to check them and the 1 and 2 cylinders
look ok a little rich but the number 3 is realy rich but number 4 matches 1 and 2 .
I checked the compression and thats good nice and even with the others .
So could this be that maybe there is an internal leak in the injector?
The plugs are about 5 days old and they are ngk bcpr7es-11 gaped at .035
and sometimes when the car idels for a couple of mins it like loads up when you go to drive it . Any input would be great

the plug wires are about 10 months old they are morosso.
