Check your oil pressure for the knock just in case. it may be a spun rod bearing or somthing major. you could check all of your pulleys. right now i have a knock coming from my power steering pump pulley. it somtimes sounds LOUD like a rod, but its not.

I just bought an 04 isuzu rodeo with only 75000 miles it seems to run rough and makes a knocking noise and shakes and no the chk engine light is on what do you suggest I do


First thing I would check is timing then plugs and wires. With electronic ignitions, even bad plugs and wires can cause rough running and pinging and knocking, backfire and such.

Where do I find the knock sensor on a 1994 cadillac deville 4.9 engine?


Knock sensor is on the right (passenger) end of the engine, and will activate if at least one of the cylinders is misfiring. Your rough running engine can be caused by many many issues - I suggest you start with plugs and plug wires.

Engine runs really rough for about 10 mins., then runs smooth until I turn it off, then rough again


Power is reduced, oil when the engine has a stuffy as small hammer knock. Serious damage the crankshaft and connecting rod, and even lead to piston broken, hurt the body and the cylinder head. Recommended maintenance as soon as possible.more go hobd2

Pontiac 2000 rough idle engine light


Depending on what year and model, you may be able to check the ECM for trouble codes yourself. Either way you need to know what the codes are.
My guess would be they disconnected the air temp sensor in the air filter box. Look for a sensor in the air filter or the hose going out to the front of the engine compartment that is missing a plug.

Check engine light and knocked off rockers


Running rough and misfiring is usually a one or more bad spark plug wires. Don't go back to that dealer. Replace the wires or have your mechanic do it for you. If you replace them, take one off at a time and install the new one. If you put the wires back on in the wrong order, it will misfire.

1995 chevy g 20 va 5.7 engine runs rough even


You may have picked up some debris and/or water when it ran out of gas. That got sucked up into the filter. Try changing the fuel filter I believe it's located on the right side, just ahead of the rear wheel.
Try that and see if there's any improvment. Hope this helps.
Good luck.

5.7 gm runs rough and back fires through the intake


I agree with the timing. Your timing is way advanced causing pre-detonation and throwing your flame front and/ or unburnt fuel out through your valves and into your intake manifold. If you have gone off-roading a lot or someone has been beating on your engine or engine compartment while the engine is running your knock sensor will advance your timing to try and fix that. I agree that you should get that thing on a scanner ASAP but I can almost guarantee that you need a timing job and possibly a new knock sensor.
