Afis problems i have a 2005 sv650. the problem im having is that on cold start it doesnt idle up to 2000rpm. when you start it it starts like its hot already wich is fine in the warm weather but in the cold it will stall. almost like its not choking except there is no choke because its injected. perhaps a prob w the afis?

What is to high? 2000RPM, 2500RPM? Also cold idle and start up idle and many other factors vary with make, model and type of engine, smaller engines in most cases need a high start up idle.

Not an uncommon issue for one to idle fast while cold but , 2000 rpms is a little higher than normal. May want to check the engine coolant temperature sensor for proper voltage and the coolant level. Also, check for small vacuum leaks around the throttle body gasket.

any engine check light on ?
could be the idle control sensor

Hi there,

When cold, modern EFI engines are designed to idle higher, until the engine warms to operating temperature. The idle should then return to around 700rpm.

If your engine still revs at 2000rpm after warming up, then there is a problem with the fuel/air mixture, or a possible air or vacuum leak.

In this case, your vehicle's computer will have stored the appropriate fault code/s. Have your codes read by your local Renault dealer to determine which circuit is the cause.

Hot or cold? 2005? CODES.
OBD plug under dash.
Check for codes.Google the codes. That's JUST a beginning,here.
IAC or cold start valve? NOT on a 2005.

idle air control valve is bad replace it. at start up choke control runs till warm up while driving throttle opening controls engine at idle ,the idle air control valve.

You are equipt with a EGR,if this valve is open at idle then you will experience rough idle and a stall at idle,

You need a 10 mil and 8 mil spanner, carb cleaner and mabie some wd40.
Remove the big hose which goes from the throttle body to the air filter housing. Under the throttle body there is a idle control valve, unplug it, spray some wd40 on the 8mil bolts and take them off. Clean the idle control valve and housing and anywhere else which looks dirty, dry it with a lint free cloth and then put everything back on.
remove the battery negative terminal and leave it off for 30 minutes, this will reset the ecu to factory settings.

On the top of the throttle body there is a black circular rubber screw cover, take that off and there should be a plastic screw.

Connect your battery and start your engine, unscrew the idle speed control (plastic screw) so it revs at 2000rpm cold. When the temp needle reached the middle so it revs at 1000rpm hot.

This should solve the problem, if you drive around and find that you in 4th gear, with your foot off the accelerator and the idle is going up and down madly then the idle control valve is worn out and it needs replacing. Cost around £125 on ebay.

Check the hoses - especially all the little 10mm hoses that connect vacuum pipes, etc.
There is a device in the throttle body called an Idle Stabilisation Valve - they get gummed up, especially on such an old car, and with NZ's low-petroleum fuel - lots of additives in NZ gas.
They are easy enough to clean - look for a lead plugged into the throttle body near the butterfly - you can unclip it and pull it out complete - they are usually about 15cm long, by about 4cm wide.
Spray it liberally with carb cleaner and make sure it can move freely. If not, a wrecker is the best bet - they are pricey new.
Good luck.
