rb25det vibration when accelerating...any thoughts?

[johnrb25s14]

I just got my swap not to long ago and a problem had basically plagued me from the beginning. At the beginning the vibration came on and off at times. Over time it got worse and worse. At one time i thought it was just maybe using an octane booster because the problem seemed to appear whenever i filled up my tank. I changed the spark plugs since they were definately burnt out and that didn't fix it.

Can the problem be the fuel injectors?? I never had this problem with my old ka motor and with this rb25 skyline motor it just got complicated. With the vibration it seems to lower down the idle. I checked the vacuum hoses and everything seems to be connected just fine.

Anyone have any thoughts??

is the vibration throughout the entire car or through the steeringwheel or what? where do you feel it?

the vibration is felt throughout the car. I definately know its not the steering or suspension. A subtle clicking noise seems to be comming from the side of the intake manifold. When i accelerate i feel the shaking from in front of me (engine).

spark plugs didn't fix that problem...

Check the motor mounts.

just fixed the problem. Seemed to be one of the plugs from the igniter chip that was covered with a white corosion, but is working perfectly fine after cleaning all the plugs in the engine bay. I also reseted the ecu for about 12 hours, which also seemed to work with my small problem of running the a/c and stalling. Im guessin the idle adjusted itself.
