High idle on startup
 

When starting my XD (if not warm already) it will redline idle for around 2-3 seconds. It has been doing it for a few months and I know its not good for it. Any suggestions?? about 83k miles

wait, so your car is idling at redline, like literally at the top of the tachometer? or it is just idling at a slightly higher rpms to warm up, which it is normally supposed to do when it is cold.

yea. it literally redlines for a couple seconds

is the xD drive by throttle cable? or drive by wire? if it has a regular cable, i'd have somebody start the car while the hood is up to see if binding or something.

Its electronic, not cable. Mine runs a little higher than normal at startup, for warm up, but never redlines. Time for you to go to the stealership..

ok thanks for the help guys.

it redlines for a couple seconds then runs normal after that. its like im pushing the gas pedal when i start it then let it go..

This maybe a silly question, but does it also look like your going 120mph? I'm just saying our cars have startup sequence where the needles jump to maximum then back down.

I don't think that's a silly question because I think he just found his answer. :rofl:

yes my needles jump to max scale. but it is revving up also.

Post a video if you can.

its not a normal rev like when your engine is running and you step on the gas.. its like a high revving noise while studdering basically.

I will take a video tomorrow while starting it

Not normal...

The studdering is the rev limiter kicking in. Have this checked out soon, running such a high RPM with the engine cold is not good in the long run.
