Blazer is not running right. Fuel seems to be sluggish
I had a 98 blazer, 4.3L; the car is about 65K miles and is suddenly acting weird and not running right, sluggish. The car was shaking when step on the gas peddle. The car is acting like this about 3 or 4 times a day and then running well afterward. I have the feeling that one of the fuel injection doesn't do it job. Can anyone tell me what was wrong with it please?
Thank you |

Re: Blazer is not running right. Fuel seems to be sluggish
The PCV Valve is located on the drivers side valve cover towards the back, It will have a black hose connected to it. Pull up on it and twist it and it should come right out. They are about $3.00 at any auto parts store.
