WTF....

On my home from work, im cruisin down the highway got the cruise control on. Going about 70, at about 2,500-3,000 rpms. Then all of a sudden the cars starts acting up. The starts like bucking.... Like its hittting a very small rev limiter? I shut off the cruise and it stopped, i then gave it gas and it acted normal ? Put it back on cruise, and it was then fine ? I have noticed it doing this on and off. but never as bad as i was tonight. I some times notcie a VERY, i mean VERY slight bucking whne the cruise is on but never for long. Anyone else get this ? What do you think could be wrong ?

Car is brand new only 1,500 mile sit, mods in sig....

 

I just tried to use my cruise yesterday and it wont engage , so I gotta take it in tomorrow my warrenty is up in like 300 miles.

 

angeltiger you need a new sensor...i had the same problem.


i have no idea what OP problem is...maybe it's the tune?

 

Yeah I need ANOTHER new sensor. I already had it in for that. Now I gotta take it in again...lol.

 

Dont know sometimes what causes cruise to go out is if the 3rd brake light is blowed or it could be a sensor.

 

that happended to me except my car died on the freeway runnign 80! they had to replace my whole PCM.

 

your cruise control can be disabled....and a DTC code set, caused by riding the clutch.
Its an easy fix, basically the code just needs to be cleared and it will work fine.
