2005 f4 wont idle

Hi guys this new issue came up today. After a long freeway ride today when I got off the freeway the bike kept stalling when trying to idle. Starts up just fine and runs fine but wont idle all of a sudden. Need some help guys. The riding season is almost over would like to get this taken care of ASAP

Ok Chris, so only at real low rpm right ?
Did you check if your throttle cables have not come undone, at the actual handlebar firstly ?
Check the caps on the throttle balancing tubes, are they in good shape, you might have a slight air leak.
Did you put the same or similar fuel in as usual ?

Could be many things but you'll have to start somewhere.

It could be a simple as Dons suggests, or it is just time for a TPS reset.

hey guys sorry to start this up again. I just pulled the bike out of the garage, she started up with no problems. Once she gets to operating temp and give her some throttle she will start to sputter and eventually die once i let go of the throttle. Does this still sound like a TPS thing?

Thumbs up ?

Vacuum leak.......
Get the manual for your bike......
The balancing tubes go from the throttle bodies in pairs to each side of the bike.... they should be capped there
If you have all the smog junk the tubes won't be capped and will continue to the 5 way fitting and from there the the fuel pump plate and charcoal canister and then the tank vent

See why you need the manual?

Here's what Noel and Dons are talking about...

Check the circled and the colored tubes for air/vacuum leaks.
