A rough idle

My 1998 Chevy blazer has a rough idle. I listened to it with the hood up and I heard a loud hissing sound which I traced back to underneath the air filter hose. What hose run under there???

Runs very rough and idles at 950 rpm, is this fast?


Sounds like a vacuum hose leak. Look under the hood for any cracked vacuum hoses and replace. listen for hissing noise.

My 2003 Chevy Malibu just started to idle very high this morning and it's hard to use the brakes. Does anyone have any suggestions?


High idle is a vacuum leak, and since your brakes are not working properly, then I can bet it's a hose cracked or broken, disconnected, pop the hood and listen for a hissing sound and replace the hose.

1998 5.7 chevy. replaced intake gasket, runs rough at idle clears up at 2500 rpms. thanks


You could have any number of problems. Sound like a lean mixture problem. Make sure all vacuum lines are connected. Make sure the upper intake is sealed properly (correct torque and tighting sequence. Spray a mist of water around the gasget area and listen for a hissing sound. If you have a scanner, test each cylinder to isolate the missfire. You may have disturbed one of the injectors and they are not firing. Some debris may have fallen into the cylinder intake port and is keeping a valve open. Plug wires may have been switched. Best thing is take it to your local mechanic.

You probably have a large vacuum leak. With the engine running, listen under the hood for a hissing sound. Check all of the rubber lines running from the intake.

I had the same problem but not with the popping sound. Try checking your vacuum hoses. My problem was with the PCV Valve elbow. It is located under the air intake hose.
