Rough idling on 2007 Silverado 5.3

It is not critical, but I is very annoying. Ever since I bought new my 2007 Silverado does not have a smooth idling. It jerks constantly now and them. It is a very gentle jerking, but it is very annoying. I still have to take it back to the dealer, but I want to know if possible the cause or possible causes for this problem. Of course of some one already fixed it, that would be great.

I don't have very good experiences with dealers, and my hopes are very slim on them fixing the problem.

Go to the autopart store and ask for a throttle sensor and an idle sensor and it should fix your problem.

it might possibly your throttle sensor... or it could also be spark plug or coil pack, depending on which one you have.

Had same problem with my 2002 Silverado. Took 2 month to find problem. Wires at wiring clip on valve covers that control each coil were taped to tight and the wires are so small they were braking apart.Wiggle the wires and see if the engine smooths out-runs rough-smoothes out-runs rough.Had to cut wires from connectors and wire direct. ran great for a couple of months than started again. jiggled wires and found a couple more acting up.Cut from connector and wire direct runs great again.I only have 2 wires left in original connector. The black ground wire I crimped an eyelet on both ends and grounded them to a bolt.

WELL YOU HAVE NEW VECHICLE UNDER WARRANTY.I WOULD SAY BAD GAS WILL CAUSE YOUR PROBLEM.BEST TO LET DEALERSHIP CHECK IT OUT.A FAULTY EGR OR IDLE AIR CONTROL VALVE WILL CAUSE ROUGH IDLING AND STALLING.BUT THOSE ARE NEW PARTS THAT STILL COULD BE DEFECTIVE.

2007 G5 Rough running (missing). Doesn't die.


Hi shoemaker.
Fuel filter issues show up in high demand fuel needs such as passing or going up hills. Rarely do they cause rough idle problems.
Is the check engine light on or flashing? A flashing light indicates engine misfire and should be repaired as soon as possible.
So you could have a vacuum leak, a stuck EGR valve, bad ignition coil, worn spark plug, and many other items.
If you don't have a check engine light and haven't done a tune up do one to eliminate a few items and see if that smooths it out.
If you have further questions ask me and I will check and answer you.

2003 Silverado rough idle, idles good after "check engine" light


Check your o2 sensor voltage, those trucks are real bad for o2 sensors, and yes if one sensor is reading 0mv, the others will start to drop out, and the vehicle will run very, rough. You also may check fuel system pressure, should be almost 60p.s.i. If its alot lower, Id be looking into a fuel pump. If that vehicle is drive-by-wire (no throttle cable), the throttle bodies get very dirty and cause that concern also. Id start by having the vehicle scantested.
