Help XR6 Rough Idle

[YNOT]

Hey Guys,
Im new to these forums, bought a ford xr6 99model 5spd.
Im not sure if you guys can help, hopefully you can.

We currently serviced the car, but still on idle the car shakes abit very lightly but enough to notice, it comes and goes.

For a few minutes it wont be as noticable then it will become more noticable.

Any suggestions on what it could be? Valves?? thats all i can think of

Thanks
Tony

Hey welcome to the forums, if its the valves it wouldnt come and go a mechanical problem would stay around. im taking a stab but i think maybe a dirty throttle body or idle speed controller. something around the t/b area is my thoughts. or if the leads and sparkys are due maybe they are breaking down.

Hey thanks, i shouldnt have used those exact words what i meant was sometimes its more noticable then other times, also sparks changed havent changed leads yet

Check your inlet manifold for leaks loose bolts ect thats pretty common

also, though this may sound lieka stupid question, as im not used to my new car yet upgrading from a sss, is it normal when taking off to hear a light knock from the diff

[blownba]

Au's are known to have alot of problems with they're diff centres. They can tend to shudder on take off accel. If your not sure get a good diff joint to drive it.

One more thing guys (i know getting anooying) the battery light on the dash has started to turn on, does this mean that mean i may be needing a new alternator soon?

Thanks Again
Tony
