R31 Rev Problem

[DC33VN]

alright im new to the skyline scene and i recently bought a r31. I took it to my mechanics and i fixed the gearbox as the syncros were stuffed and it wouldnt go into 4th gear. I also changed the thrust bearing because it was crap. I told him about this rev problem i was having and he said he took a look and it was fine but just before it happened again on the way home. I turned into the street and went to 4 grand revs in 2nd and then i took my foot off the pedal , the revs just stayed there without dropping so i tried to put the car in neutral and try 2nd gear again and the same thing. then i turned it off while it was rolling in neutral and then turned it back on and the revs just bounced back to 4 grand. i parked it after i knew that there was somthing wrong and let it sit there for about 2 mins and i put my foot behind the pedal incase it was stuck and thats the reason it was giving me 2 grand revs. i did it and they fell down to 2 grand. after i thought its better so i proceeded to head home. got to the next street and stopped fully and the car was back to normal. i have no idea what this problem is and im paranoid incase it happens at the wrong time and something happens. Does anyone have any idea what the problem may be?

the cars a 1987 r31 sillo 5 speed with extractors exhaust other then that i have no clue whats been done.

just talked to my mate and he either thinks its the throttle cable thats jammed , could it be it?

yeah it could be the throttle cable or the butterfly that is getting stuck and causing the higher revs.

i think iv found the problem it seems its my pedal , got stuck again tonight at 2 grand revs and i kicked it up from underneath and it went back down to normal idle so im going to probably get a new one or maybe a whole new set

problem solved it was the accelerator cable thats stuffing the revs up, getting the part ordered in and fixed and i also got the car tuned up a lil and the difference is amazing
