Tachometer on my 2006 Pontiac torrent isn't working


Outside chance there is a wiring fault or the engine management ECU has developed a fault but most likely the tacho is defective and needs replacing. You need a guy to check it with an oscilloscope before you start spending money needlessly.

Had body control module replaced on 2001 pontiac aztek now the check engine light is on constant. codes indicate it could be a map sensor or an oxygen sensor is there a testing method for these and how do...


There are ways to test anything on any vehicle

That can only be done with knowledge,scan tools,
oscilloscopes,& vehicle reference material, such as
Alldata or you having all the factory service manuals

You can not work on todays vehicles by changing
parts, without doing any testing

The misfire is more likely ,ignition issues. If injector cleaner really worked ,the manufacturer would recommend it ,in the owners manual. Check for codes ,and look at the spark and injectors ,on an oscilloscope.

1993 galant will not start when cold can mass air flow be tested?


Hello.... Yes the MAF can be tested... But to do it accurately you need a oscilloscope so that you can see the frequency response.

Hope this helps...
