as far as the temp gauge goes...i have a 91 1500, i had the same problem. i replaced the temp sensor and it fixed the problem.

as far as the bad gas mileage... if you haven't already done so, perform a tune up; plugs, wires etc.

SOURCE: 2005 chevy colorado runs rough and gets bad gas mileage.

Sounds like it needs spark plugs and wires, and a fuel system treatment.

Suspect worn valve guides/seals causing this issue. You may need a valve job to correct this issue. If high mileage on this engine, rings could also be an issue and the repair will be expensive

02 impala gas mileage between 10-13. Abs/ traction control lights on... ac also blows only cool on passenger side. Hot on driver side... already tried charging worked only for a few minutes. ..HELP


Abs and traction control work with each other. You have a fault in one of the system need to get scanned.The a/c have a blockage in system or maybe a leak. The gas mileage probably has to do with abs/traction control

depending on mileage, but possible tune-up could fix it. if already done then check ignition coil pack and ignition wires also spark plugs, check vacuum hoses for leaks or porous, last injectors clogged - use some techron fuel injector cleaner (wal-mart has them). have worked at G.M. dealership for over 15 years, saw that alot.

Burning alot of fuel 2001 chevy impala 3.4 engine. Check engine light on. recent tune up. 95,000 miles. Car also hesitates highway acceloration. Thank you.


First....you will have to check the code(s) stored in the computer.
The check engine light is telling you....you have a problem and fixing that problem may help with your fuel mileage.
When the check engine light is on....you loose 20% gas mileage and have 20% higher emissions.

Usually when it comes to bad gas mileage, an air filter change, fresh oil and filter, fuel filter and making sure you have no vacuum leaks....

Also, believe it or not, improper tire pressure will affect your gas mileage.

New spark plugs and wires are a "nicety" but if there is not damage to them, then they will be fine.

Where is the PCV valve on a 2002 Chevy Impala?


This sounds like a possible bad fuel pressure regulator.
Depending on which engine (3.4l or 3.8l) they can be easy or hard to replace. For pics on the 3.4l regulator replacement, see this link...
