I was coming up on to the highway on ramp and I jammed on the gas and the gasd pedal did not return it stayed floored I tapped on it a couple times but it was not good I then had to reach down and pull the gas pedal up. My engine hit the rev limiter about 4 times what could be causeing this? Could it be a sticky throttle cable or maybe malfunctioning cruise control. Any help would be appreciated boy was it intense I almost wiped out the car in front of me. Oh yeah my car is a 1988 Mustang GT.

 

The pedal has a cable that goes directly to the throttle body. The throttle body has a spring on it and their should be an additional saftey spring as well.

 

Ya i have had it gotten stock before but it was right after i did the Intake Manifold so I just looked and adjusted the throttle. The reason for me was that the new chrome valve covers that i have are just alittle too high and they sometimes tend to hit the spring for the throttle on the throttle body.

 

I haven't touched anything close to the throttle body so maybe the cable is just gunked up or something the wierd thing is it only happened when I had it at WOT when I tap on it it bounces right back.

 

ya but one day it is not going to bounce right back. so i would try to find out the problem with it untill one day your foot slipps and hits full and it does not stop and you smack into the back of someone or say hello to a tree or pole. I have seen too many Mustangs hit trees or poles. hmmmm.....

 

Oh there is no doubt I want to fix it I was just hoping to get some ideas on what to look at I already lubed up the cable what else should I look at.

 

you might want to clean the throttle body out good with some carb cleaner, there is a lot of junk that builds up behind the butterfly from the EGR valve bleeding exhaust gas into the spacer behind the throttle body and there is a chance that there is enough of the gunk to hang the throttle plate up at WOT. on ocassions, my gas pedal would hang up on the carpet or floor mat if I let it slide up under the gas pedal, so check that this ain't your problem also.

 

Sound like the return spring..[:'(]

 

i had my 88 gt do that twice, my floor mat worked its way to block the pedal twice, it dont do it no more since i ripped it right out after the second time.... should of done it the first time[:@]
