Hello

I was just windering what are some ways to get better throttle responce That wont make my wallet cry lol? I step on the gas and it slowly gets up to speed. 95 f150 with a 5.8l engine stock for the most part.
Thanks for any help.

 

Does your truck have a throttle cable (runs from the gas pedal to the throttle body)? If so, that may just be out of adjustment and needs tightened up.

 

Oh ok I will have to check that and see if it is would it be in the chelton repair manuel on how to do that? If I do

 

When was the last time you did a tuneup on the rig?

A 5.8 should move that rig around smartly.. if it's in top running order, check codes, check fuel pressure, give it a tuneup, check the timing, do a 6-liter tunup, add headers and an exhaust system.

 

Well iv only had it for like 2 months so I dont know.

Thats what I was thinking but I press the gas pedal pretty far down and quick but it just slowly gets up to speed though it would have more holy cow close to wipe lash event lol.

So what does a tune up entail? Something I should have a pro do? Thanks

 

Throttle response have never been especially good on theese engines. There is a noticable pause between you pressing the pedal until the engine revs on a stock setup, there just is.
But it shouldn't be big, just enough to notice it.
By the sounds of it though you've got more than that? You could check the play on the throttle cale, just get a friend/parent/doughter/neighbor/whatever to press the throttle and check at the throttlebody for any excessive free play. If it's clearly too much, adjust it, should be a pretty obvious adjusting screw or something similar around the cable.

 

Three questions.

What is your rear axle ratio? If you don't know, post a picture of the sticker on your driver door jamb. We need a clear picture of the AXLE CODE.

What is your transmission? If you don't know, post a picture of the sticker on your driver door jamb. We need a clear picture of the TRANS CODE.

What size tires are your running on this truck?

 

Also, you could have some other problem such as a slipping transmission or clogged cat. While it's no rocket the 351 in my F250 moves it along decently. FWIW I don't have any noticeable hesitation or lag.

 

throttle response? long tubes.

pacesetter.

 

It could be a transmission issue, maybe its not down shifting like it should.
Like some one else said the catalytic converter could be a problem I had one before that the honeycomb melted and made a pretty bad restriction.

 

Tires are 31x10.50x15

 

I blame the EFI setup in general. World of difference between my EFI 302 and my carbureted 302. Carb'd one had a very crisp, quick throttle response and decent acceleration, in stock form with a 2BBL. My EFI one may have more power and a little better acceleration but the throttle response is terrible. Takes a second to wind up and also slow to wind back down.
