My tahoe will barely start and when it does it says the engine is running on half power. What does this mean?

Have it scanned for trouble codes and post the codes for me. You will probably find a code for the TAC module.

How much should this cost to have it scanned? Is adding injector fluid to the engine a good thing?

Autozone will scan it for free, but they might not be able to read some codes. You could also purchase a scan tool from our tool store. Click on the link below to visit the store.
