07 runs bad when at red light
My 07 w/ 65,000 miles on it has be getting worse with time. When I pull up to a red light i feel a vibration in the whole truck. The steering wheel and brake pedal are what I feel and see the most.
I have had it in the shop several times and they say it is normal. Seem like it idles about 150 RPM's too low. Anyone else have that problem?

Re: 07 runs bad when at red light
A rough Idol is NEVER normal...!
easist way to solve that is avoid RED LIGHTS...
Next way is take it to a shop that cares...the one your going to right now doesn't seem to care....

I have had it in all three shops in the Dallas Fort Worth area. I even called GM about the problem. They all say with out a code or warning light their hands are tied.

Re: 07 runs bad when at red light
Maybe you got some bad gas ?or someone put something in your gas tank
Put in some dry gas/fuel injector cleaner run it low and fill up at
at a different station and see what happens.
Cloged fuel filter/injector or air cleaner
Bometimes the throtle body flap om the intake gets a carbon build up(theres a pin hole that gives air at idle when flap is closed,sqwert some spray fuel injector cleaner in and around the area.
Bad plug or wire(i would think they would cause a code to come up))
All cheap maintenance type things to check and do they couldnt hurt

Re: 07 runs bad when at red light
as i was saying earlier...both of mine idol correctly...you can try a fuel additive or injection cleaner, change the fuel filter, check for loose connections to the plugs, burn a tank of premium and if all of that fails go to the dealer and have the mechcanic take a ride with you...first off go to StarBucks and buy Him a large latte and a muffin then hit a bunch of red lights...take a mechcanic, not the service writer...and by the way, settle on only one dealers and make sure you bring your REGULAR Service Writer (always use the same one) a bottle of WINE every June and just before Christmas...

Re: 07 runs bad when at red light
Thanks for the info, I do keep up with good mantanance on the truck but this has me stumped. The rough running seems to be after warmup and has progressivly gotten wrose over time. I know the I5 has a little vibration but not this much. I'll keep posting what I find.
What is the correct RPM at idle?
