good ole cruise conrtol

[Crimson Fury Z]

aint working. i hit the button, the rpms hold, and the speed struggles to hold. turn it off, and the rpms will match the speed again.

 

i.e; hit @ 60mph, rpms hold @1900-2000, speed struggles between 55-60mph

Does it happen only when climbing up hill? Is it normal when travelling a flat road?

 

You might want to check your transmission fluid level or probably the transmission needs new fluid and filter.

Do your heater controls work properly? If not you have a vacum leak somewhere.

Hold it...maybe thats why my heater controls don't work....my cruise controlis f'd up too

 

any ideas what lines i should check for vacumn leaks

[Crimson Fury Z]

well, the lighting on the HC is out, and it is only doing heater and defrost...

Check the line that runs from the vacuum servo under the hood to the vacuum ball under the battery. That's where the one on my Olds was cracked. I cut it, stuck a hose with a nail plugging it up and bingo, good to go!

 

Good luck.

aah, thats the ball's purpose! reminds me of like the toilet ball that makes the water stop after a certain height

i had the exact same problem just today the mechanic yesterday forgot to hook up one vacum line that controls the heats and the cruise he hooked that back up and both work fine it was a llittle line about 1/4 in wide right behind the top of the engine.
