heres my issue

Chassis: 1990 240sx
Engine: 1996 engine
problem: bogging out at 3k rpm under load (when in gear), not reving up smoothly

now be4 i get jumped at here is wut ive done so far to avoid asking this

Compression test: 190 190 190 178
airleak test: tight as a virgin
EGR: blocked off completely by ebay steel plate
TPS: good (borrowed from friends car) working TPS set at .5 at idle
Injectors: working properly, even used stethescope to hear em
Spark plugs: NGK V power ( ithink) were brand new now have blow by and whitish tip, which means running lean i believe
thermostat: new
plug wires: new NGK
Timing: Stock 20BTDC setting
fuel system: new filter,strainer, and pump FPR reads 40psi at idle
MAF: proper voltage and works great, borrowed from same car as TPS
Grounds: all properly bolted down
exaust: no black smoke or any kind that would indicate blown H gasket or coolant leak
Temp sensor: did FSM way of checking if it works ( dipping in boiling water with thermostat) and is functioning...
ECU: was only throwing EGR nothing else

any body deduct anythign from this...ive gone to other forums and searched here aswell... worst case scenario id have to guess Knock sensor...whihc means ripping off intake mani...which i dont wanna have to do... anyother possibilities im more than willing to listen... :soapbox:

check for vacuum leaks.

its been air leaked 4 times after egr assmbly was removed...

hennce my original post:tight as a virgin...no leaks man

I'm gonna have to go with you on the knock sensor theory. Just solder a resistor in there.

Check your fuses? WTF? The anti bog control fuse?

haha ry tellin it how it is. yea, imma have to say wire a resistor in the knock sensor

What resistor would you wire in for the knock sensor ?

i took all the air lines that go to the intake manifold except for the brake booster and fuel pressure regulator. my car also bogs at around that rpm. all i do is let it warm up and its good. hope that helps.

Still wonderin what resistor you would wire in cause that knock sensor is a pain in my ass

I can't remember offhand, but i know that if you do a google search something will come up.

so did u fix your problem??...cuz i have the same:(
