rough idle fixed

2005 scerw with 4.6l 75,000km
Had it to dealer several times for rough idle,they replaced tps,tcm,fuel filter. cleaned throttle body cleaned maf, they finally said "that's the way they all idle
sorry about your luck.." Borrowed a buddies snap-on fuel injector cleaner system, ran ac-delco upper combustion chamber and fuel injector cleaner through it. Truck has never idle better.

Welcome to the site. I took mine in for plugs and they reflashed the pcm. That took care of my idle problem.

Such is life. Just passing through.

Welcome aboard!
There's a "Stealership" throwing parts at it again...
Will you be changing your spark plugs out at 100,000 k's?

Press on regardless!
