New With Questions

I have been on stang net awhile but now I've made an account to ask questions about a foxbody I'm working on. I have a 1988 lx 5.0 it has an off brand type aluminum intake and aluminum valve covers my problem is that when you step on the throttle the first inch seems very stiff compared to the rest of the throttle someone said it may be because it's not tuned for the intake but I think it seems like a TB or cable problem, any suggestions

Let me move your thread over to the fox subforum, bunches of gearheads that can help you out there.

Seems like either the throttle body is hanging up or the cable is sticking.

Remove the cable end from the throttle body and move the throttle by hand...then get inside and push the pedal ( with cable disconnected )

Agreed with above. Check for it hanging up someplace or needing lube

Cable issue. You'll have to pull the cable off and possibly reroute it so it doesn't bind up like that

I agree, that cable needs a tune.

Is the car auto or manual trans? If it's auto, the TV cable and TV valve for the transmission could be a factor.

its an automatic thanks for the information ill check the cable soon

 

[JD1964]

Automatic, so there's also a throttle valve in the transmission valve body that could be sticky. I would check for free cable travel for both cables individually. Try an isolate if resistance is coming from one or the other cables.

 

[Mustang5L5]

The throttle cable is pretty simple to unclip from the throttle body. All you really need to do is unclip it, then you can isolate and see what the resistance is from. If the throttle cable is hard to move, unhooked, then the cable is the issue. If the throttle blade has resistance, it could be the cruise/TV cable.

Also, cable routing is key. Since the intake has been swapped, it's possible the throttle cable is routed in a bad way causing it to bind up

How do you tune a cable anyway.....

 

[General karthief]

Cable dyno, come on man, get with the times. You can shave .000050 off your et with a well tuned tb cable. Just ask your fb friends.
