Buick - Introduction to OBD II (1998)
This video, taken from Buick's Know-how Series (KH-219), introduces details
of emission controls and the On-board Diagnostics Generation II (OBD II)
system, particularly for mid-to-late 90s Buick models. Topics covered

proper Powertrain Control Module (PCM) operation, and general
ECM/PCM Computer Replacement
Engine control computers can be complicated and frequently high-priced
products. Avoiding unnecessary replacements and warranty returns are
important to professional technicians and consumers. Most problems
resulting in warranty returns can be avoided by following the proper
Before, During, and After installation procedures.
How to Determine the Effects the PCM has on Long-Term Fuel Trim
The PCM can adjust long-term fuel trim to change the injector pulse
duration to account for gradual changes in operating conditions. When an
orifice becomes severely restricted, misfires can occur. Watch this video
for professional automotive instructions on how to determine the effects
the PCM has on long-term fuel trim.
1966 Buick Convertible Barn Find Rescue, Part 1
This is the story of a '66 Buick Special convertible that had been
abandoned in Arizona in 1978 by the family of Rick Pewe, editor of 4-Wheel
& Off-Road magazine. In 2011, the guys from HOT ROD Magazine, in
conjunction with Rick, spent four days bringing the car back from the dead
with plans to drive it home from Phoenix to Los Angeles. This is part 1,
with the hacking fun the guys had rescuing the car. Look for part two,
loaded with road-trip hilarity. The story is printed in the September 2011
issue of HOT ROD Magazine.
How to Reset the ECM
After watching the Smack resetting the ECM and getting a huge increase in
mpg, I started looking up how to reset the ECM.
There are a few different ways, but they all pretty much say the same
thing, just in different ways. The majority of the info I gleaned was from
high performance car sites where people add after market parts and need to
reset the ECM so their vehicles will adjust to the new equipment and
variables. Hopefully this will help us with our cells/systems.
