How to replace a crankshaft sensor on a grand prix gtp
This video is dedicated for the GTP owners that need to do the same
crankshaft replacement procedure as I am demonstrating. I hope this video
helps anyone out there that needs to tackle such a job and the video also
shows that it can all be done with simple tools which in turn will save you
time and money.
1996 Buick Century Camshaft sensor Install
Changed the sensor, car still miss fires. im starting to think some things
going on with the injector but i already changed cylinder 6 but same deal.
this is really stumping me.
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.
BTW I am NOT a mechanic or an electrician - IOW this is for informational
Use at your own risk cause I am not liable for anything you do.

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.
