Nissan GT-R Engine Assembly
Here are some quick scenes from the Nissan Yokohama engine plant's Clean
Room. It takes an average of 100 minutes for an engine master to assemble
one engine. Each man diligently checks and records the torque spec of
every critical nut and bolt, and the data is stored for the life of the

Fuel Trim (SFT/LFT) vs. O2S B1S2
Me and my friends (Colleagues) repeatedly faced with the fact that the
faulty O2S B1S2 (downstream Oxygen Sensor) was the cause of the DTC P0171
on Lexus RX300 2001MY.
This video (Russian with English Subtitles) shows some of the checking ECM
parameters with faulty probe ( O2S B1S2), by using the "downsream O2S
simulator", before and after installing a new O2S B1S2, and the results of
the active test "A/F Control" by Toyota Techstream.
Looking at GM's Direct Injection Engine Technology
GM's direct injection engine technology increases fuel economy and power
while reducing emissions. Watch as Global Chief Engineer Chris Meagher
explains how it works and talks about how this technology will soon be in
ten percent of GM's vehicles worldwide.
Troubleshooting fuel pressure problems on a 2002 Intrepid
READ THIS BEFORE COMMENTING! This issue was solved....read on:
My car has an unusual problem. It gets the same fuel economy at 90MPH as it
does at 60MPH and it doesn't like to start when cold. The malfunction
indicator light is not on and there are no stored DTCs. Once the car is
warm, it runs fine except for bad highway fuel economy. (21-23MPG instead
of the usual 25-28MPG) .
I think we found the problem. The fuel pressure is out of the specified
range. Chrysler says the fuel pressure on the LH platform cars should be
58PSI +/- 5PSI..... this car ranged from 36 to over 75 PSI. It's time for a
new regulator. These cars have returnless fuel injection so the regulator
is not on the fuel rail, rather it's built into the fuel pump itself. As
the RPMs increase, the pressure stabilizes which explains the bad fuel
economy at lower speeds and OK economy at high speed. Replacing the fuel
pump assembly (and thus the regulator) fixed the economy issues.
The no start was a dirty IAC. The pintle was worn so I replaced the IAC
motor assembly when I cleaned the throttle body.
The gauge is an Actron/Sunpro unit picked up at Sears for $40.
