minor throttle response issue

usmcsawgunner · May 27th, 2007, 07:19 PM

so this is my first 5.0 and im not sure how quick the throttle response is supposed to be but theres about a half to three quarters of a second before the engine starts revving... question...is that just normal? and is there any way to speed that up?

Thats sounds slow. maybe adjust timeing or air to fuel ratio. also could be a bad plug

usmcsawgunner · May 27th, 2007, 07:32 PM

how do you adjust air fuel on an efi?

cams-shelbycobra07 · May 27th, 2007, 07:36 PM

a tuner or computer but efi ussually doesnt have that problem as much

usmcsawgunner · May 27th, 2007, 07:40 PM

yea thats what i thought...how much is one of those self tuner things?

nah, if it was an air fuel mixture prob. then u would most likely hav a vaccum leak causing a lean or rich mixture at the o2 sensor.
is it an automatic or a manual, manual usually respond a whole lot faster than automatics depending on wht gear ur n. but check ur linkage under the throttle body, it could be binding or somethin, might wanna check plugs and re gap the also
