Need Help. VQ25de diagnostic etc...

[DR78]

Hi guys,

Im very new to nissan. Just bought a Naza ria with nissan vq25 engine. I feel lack of power, feels rough( vibration ) and not confident with the car. I thought of sending in for a diagnostic test to check the ecu see got any problem with the engine or not and maybe get the wiring recheck and maybe clean the MAF ( is the a MAF in this engine?) and throttle body. Can anyone recommend a good place to do this? Btw reg the VQ25DE engine, how reliable is it and what are the common problems?

Hope someone can help me.
Thanks in advance everyone..

the DIAGNOSTIC can be done with any mechanics that has the device, do ask your mechanic first.

the engine is reliable, common problems i see around are oil leaks from valve seals, and oxygen sensor.

could the vibration due to the mounting? as the Ria's mounting has to be modified to fit this engine.
