2001 chevy blazer keeps bloging out


Make sure all your vacuum hoses are connected and in place, also might want to check out the pcv valve usually located on the valve cover. You can also have the fuel regulator checked out... hope one of these things takes care of your problem.

My 1992 chevy g20 van surges and i'm not sure exactly why. I changed the pcv valve, fuel filter, spark plugs, and air filter. What are some possibilities


My first thought would be a vacuum leak in one of the hoses. Rubber hoses get brittle with age and even a small crack in a hose may cause surging. Happened to me in a Lumina.

Ai have a 88 chevy s-10 blazer it stall when i drive a block like it starts to cut out does it need a fuel filter, if so is it under the truck or does it need spark plugs only or does air filter only...


I suggest a full tune up.

1. Air filter.
2. Fuel filter, carbureted engine filter is located inside the line fitting where it attaches to the carburetor. Fuel injected engine filter is located in-line under the truck near the tank.
3. Oil and filter.
4. Spark plugs and wires.
5. Distributor cap and rotor if applicable.
6. PCV valve.

2002 chevy blazer fuel consumption


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.

Dumb question: where is the pcv valve


PCV Valve sits on one of the Valve Covers.

Side Question: Sounds kinda like a tune up is in order. Plugs wires fuel filter.

Hope this helps! Let me know if you need more help!
