throttle cable adjustment

[vixtoy]

i recently adjusted my throttle cable for a more stiff throttle. works great and i love the feel, but now my cruise control doesnt work, how can i reset my ecu or my cruise control module to get my cc back since what i think happened is i went past the cc's set spots to where the throttle cable trips the cc or the ecu, i dont know, but someone please help

no you also have to adjust the cable in the cruise control assembly... follow the throttle cable back and you'll see what i mean...

Just FYI - OVER tightening your throttle cable can lead to rough idle, stalling, and P0505 codes. Key word is CAN - theres a very fine line between tight and too tight. Just lettign ya know.

Curious, how do you overtighten a throttle cable, do you mean taking it off idle?

Yeah, it seems half of the people out there who tighten it report back, "I tightened the throttle cable and it is way cool, but now the car idles at 2000 rpm."

If you tighten it until the throttle is open, then you went to far (they never believe me).

As for the problem with the cruise, I supect the cable was tightened at the throttle body, but not in the cruise unit, now there is too much free play in the cruise.

What he said. Even though CTP is a learned value with this system you CAN still tighten the throttle to where it never truly achieves CTP. This can also cause high idle, hard starting and other issues.

Griffin is correct. The idle is learned. Some of the folks reported that later, the idle returned to normal. I attribute this to either, A) the cable stretched back out (it gets where it is for a reason), and B) The ECU has adapted the amount of air bleed through the idle control valve.

Myself, I'd rather have 100% of motion in the throttle than 75%.

It was bound to happen sooner or later... :evil:

good way to check if it's tight enough:

have someone sit in the car, and floor the gas pedal (car can be off). have your hand on the throttle, and make sure it's at WOT. fool around with it a bit to make sure.

that's all you need. i don't see the need to tighten it for any other reason.

Cool point, that does make sense. Been wondering for some time how I'm gonna be able to check this out.
thanks

alright fellas, i got it, to get your cruise control back, simple little thing you can do is to disconnect your positive terminal to your battery for 10-15 minutes, this will allow your ECU to reset itself, and think that the "New" cruise control settings are factory! My cruise control actually works now Yippee

[gts24]

Actually you don't have to pull your neg battery terminal to reset the ecu.

there's a fuse you can pull to do it, do a search and you're set.

this way you don't lose your clock, or any of your radio presets.
