Throttle response

[Kkirwan71]

The throttle response in my 2000 z71 5.3 truck isn't what it should seem to be. Is there a fuel filter on these trucks or what should I look at servicing?

Yes there is, driver side inside the frame, middle of the truck

Also look at the tightness of the throttle cable

How do I judge how tight it should?

Does your truck have a throttle body spacer? That will help

Should be taut, might take you and a friend to check, have buddy step on the gas and see how far it moves when he has pedal to the floor and check by hand at the throttle body and see if it can open wider when buddy has foot to the floor

No spacer it's completely stock

Putting one in may help, try what I said, good way to check if it's the right tightness

Will do. What about injectors for these trucks?

Have to research that, I think Bosch or ac Delco would be good

When's the last time you checked plugs and wires?

I've only owned the truck for two months

Little over $117 later my problem is solved

What was it? Did you take it somewhere?

Had it serviced along with a new fuel filter and air filter

Hmmm I think I may change my fuel filter then, I need to see what my 05 has for fuel filter set up, different than my 02

Mine was on the driver side on the frame about where the driver door is

I think they changed it in 03, the 99-02 is on the drivers side inside the frame, I think 03-06 have a filter attached to the pump and it can't be changed, I need to confirm tho

A buddy of mine has a tuner that also scans should I attempt to tune anything?

No, handheld is ok but you'd get better results from a black bear or similar tune where you send your computer away and they tune it, also with some handhelds it basically replaces your stock time with a new one and then if the tuner is removed your stuck in the last mode it was in until you put it back on and change it

Handheld is also fixed, like has to be in one of the modes not custom, where the black bear they will do whatever you want pretty much
