SOURCE: trouble code

DTC P0420 Catalyst System Low Efficiency Bank 1

You will find a bad O2 Sensor behind the converter or a bad catalytic converter on the bank 1 side of the exhaust manifold. This is the one on the drivers side.

SOURCE: Vehicle start shaking and died. Has a trouble code P0300

Error code P0300 means that you are having multiple/random cylinder misfires.  I would start with changing all of the spark plugs and see if that will fix it.  You will have to have the code reset at an auto parts store.  If that doesn't work let me know and we can progress down the line.

SOURCE: my 2004 gmc sierra detected a PO200 and PO300

po200 is a injector circuit issue. the 300 is most likely related to it.. There is a good chance you have a PCM issue that needs to be looked at. No way to tell whats going on without diagnosing . This will leave you stranded if you don't deal with it soon

SOURCE: i have a 2000 gmc sierra 1500 2wheel drive engine

A P1415 indicates a problem with the A.I.R. system. This code is a common indicator of an electric a.i.r. injector reactor problem. Sounds complex but it's not. There are two of these reactors on your engine. They are the black things that the secondary air pipe plugs into at the exhaust pipe/or/exhaust manifold. It is worth changing both of them becauses if one fails the other is not far behind. It is also worth replacing the factory hose clamp with a regular one---you'll see what I mean.BTW--P1415 specificaly indicates a problem with Bank 1 of the A.I.R. system. Make sure both sides of the A.I.R. system are in order--meaning all the hoses are tight and secure--no leaks--cracked hoses ETC.

7E8 and 7E9 these are not codes what they are are system 7E8 is for the engine powertrain and 7E9 is for the transmission powertrain, go to the menu 7E8 if it list a DTC (diagnostic trouble code) select it, and it would read a P code such as P0XXX or P1XXX same

I have a 2008 Saturn Aura. Its throwing 2 codes, $7EA and $7E8. 2 mechanics in my home have never seen these codes.

Honestly, no idea acout Saturn Aura's error codes.
But, looks to me that those two mechanics you called are not really very efficient,
Guess you should look for a GOOD mechanical service and get your car's computer scanned by someone who really knows how to use a scanner,

2007 chevy impala codes coming up are 7e8 and 7ea. what do i look for

Seems to be a scanner component ID, not the OBD2 fault code.
You need to learn to use the scanner and interpret the readings (usually the scanner manual contains the meanings to these codes)

Otherwise you need to take the car to an independent service with Chevrolet specific scan tools or a Chevrolet dealer, for proper diagnostics.

I have a 2007 CHevy Impala 3.5 lt engine. The engine light came on and we checked the codes and the code came up $7E8 and $7EA. we believe these are generic codes and the $ could be optional

7E8, 7EA. Cat failure.
- Check the health of catalytic converter.
- Check for cracks in muffler.
- Check air leaks.
- Check back pressure of the tail pipe.
