On 2001 chevy s10 2.2 4cylinder. It constantly makes knocking sound and idles rough and smells like its flooding. Knocking does not change at all when in gear or parked. Could it be bad knock sensor?

No it's not the knock sensor , sounds like you have a bad bearing in the engine , - rod bearing !

SOURCE: knocking noise

If the knocking sound is coming from the steering wheel area itself, then I believe it's the nylon bushing in the steering colum. My friend had the same problem with his truck. The other trucks we work on at the shop seem to have this common problem.

If it's sounds like its outside the truck, have the tie rod ends checked out.

SOURCE: 2004 chevy cavalier makes a ''knocking'' sound

This could be any number of things. It could be your CV axle going bad, your tie rod joint has gone bad, your lower ball joint has gone bad. More than likely it will be your CV axle. What you need to look for is rips on any of the boots for these parts. The one that has the rip will more than likely be your problem. Just check for grease coming out of any of these parts and you will find your culprit because it has dried up and is causing the knocking sound. Let me know if you have any further questions. Thanks for using FixYa!

1992 Buick Lesabre Idle Problem/ Bad gas mileage


If there is no "Check Engine" light try a bottle of good injector cleaner in your gas, or cleaning the throat of your throttle body with a good spray cleaner. If the "Check Engine" light comes on then put it on a code scanner and that will point you in the right direction.

1996 chevy s10 4.3 vortex lifters knocking at start up but goes away after 10 minutes idling. changed oil and filter oil pump reads 58-60psi at idle and seems to be working.


High milage? Try engine cleaner, run for couple hundred miles and then use an additive like Restore. If it's just dirt this may help. Make sure you are using the correct viscosity oil for winter temps. If it's from wear only parts replacement will fix it.

1992 GMC Sonoma - 4.3l cannot start after stall and knocking.


Sounds like an engine sensor, EGR valve or O2 sensor has failed. First thing to do is to look at the engine trouble codes to pin down the failure. You can usually borrow an OBD1 code checker from your local parts store.
