Default cruise control and other problems...

i just got an 85 supra, and everything is going great, except i can't seem to get the cruise control to work properly. what happens is that i set the cruise, and it will stay activated for a few minutes, then the speed will start to waiver, and then it will give out completly. my guess is that its a vaccume line, but i don't know where to start looking. any help would be great. the other two problems are that it seems to miss or pause at around 5000 rpm, someone told me it was something to do with valve lifters or something, it really didn't make sence to me, so any ideas would be appriciated. the other thing is that i need two trim peices forthe body pannels of the door, if anyone knows where i can get them i would appriciate it. thanks

sup castle, i feel ur pain about the cruise control, mine dont work at all so ur better of than me. I can help you with the trim thought, i had the same question when i repainted my 85, i asked the guy if he had trim like this, he went back and grabbed trim that looked identical.. he just used strong ass double sided tape and put it on, looks brand new. had them on for a yr so the tape wont give out trust me. anyways you can try that i got my car done at maaco

well... with the auto to manual thing... i thinkt here's a 2nd switch which needs to be wired up for cc to work

as far as cc not working and wavering...

check the throttle cable connections, check vacuum, check plugs and wiring going to plugs etc

i'll see if i can come up with anything intelligent later lol

for the manual swap here is the diagram for rewiring cruise control in

admittedly it's for a 1990 mk3 but it may help
