ChuckH, OffroadX,

I'm back from automotive forums (I'm now registered as 20-100 same a here) Chuck's How-to guide about Ignition timing check/adjust is excellent but it completely disagree with what's written in the Haynes manual
Quote:
for the 2000 3.3L engine they dont say nothing about disconnecting the TPS (Throttle Pos. Sensor) but to put the engine in self-diag mode (screw on the side of the computer.
For the 2001, they also request an operation to disable the PCM control of the timing but I need a monitor tool to perform it.

Someone tried ChuckH solution on a 2001 and validated with Nissan approved procedure?
