Slight RPM Flux

[JamesT]

At idle, i am starting to get a slight flux in the RPM's. Happens more so with A/C on. Im thinking its time for a fuel filter and a injector flush. Any thoughts?

I think most cars/trucks RPM adjust when the A/C system comes on? Is it somthing that is pretty wild...like a 1K spike in RPM?

I agree with the fuel filter, if yours is an 03. I also suggesst a throttle body service. That will help a lot.

Had fuel injection service....HUGE differance! Problem solved!

I watched em do it...the hook up some hoses and run cans of cleaer througj=h each injection port...KB charges $260.00 I got it done for $80.00...so let me know if you need it done seth...

So here is a question that I haven't asked before, what makes up a fuel injection service?
Do they pull the injectors and clean them or do they just dump a bottle of fuel additive into the gas tank? Or is it something completely different...same question for a throttle body service.
