Having problems with your 2008 Chevrolet Silverado 1500 2WD ?

Engine Misfiring. Rough Idling. Losing power going up hills. Engine light flickered one day. I brought it to dealer. They said cyl 5 had a fouled spark plug. They replaced it, retuned and cleared code. Drove great for a few weeks then started running little noisy (as in exhaust rumbling). Engine light came on solid. Brought truck back in. They cleaned injectors and reset computer. Ran better for a couple weeks, but in general has been a little noisy (as in combustion/exhaust rumbling no

It sounds like it could be a bad coil pack that is used for number 5 cylinder. It could also be a bad spark plug wire. Does the weather seem to make a difference? Try this quick check once night time comes around. Open the hood and start the engine. Fill a bug sprayer with salt water and spray the plug wire while the engine is running. If the wire is bad, you might notice an electrical arc from the wire to the engine block. The engine will probably start running rough. If this occurs, then the wire should be replaced. If it doesn't, then the coil pack can be tested with an ohm meter. I hope this information has been helpful to you. Good luck with your problem and thank you for using Fixya.com.
