idle speed
« on: 21:59, Mon 07 July 2008 »
hi does anyone know what these beasts should tick over at as i can adjust the carb to  whatever. i currently have it running at 1000 rpm on idle, however the car likes to fluctuate its revs between the 1000 and 2000 on its own. its going to get re jetted at minisport just wondering if this is a common problem .

I asked k-tec this question once & they said between 1000 & 1300 depending on how the car runs on idle.

750rpm is the factory set idle for the car though depending on the exhaust or other mods this may vary after. i would say 1000 or higher is a little faster than it needs to be if the car wont tickover well at 750-800rpm maybe have it tuned up? unless there is some drastic mods in there?

Ignore the standard rev counter, it's probably telling lies anyway. Just go with what sounds right.  8)

I set mine up at 800 according to the rev counter and it felt like it just wanted to conk out, it now sits on the 1000 and all is well.

This was with new plugs and good ignition circuit and the correct mixture settings aswell.

If it's hunting then it has an air leak or a blockage by the sounds of it, check for leaks & take the idle jet out & clean it.

thanks for your replies, yeh i think the rev counter is a waste of space my car is running 200 bhp and at 1000 rpm idle it sounds like its going to conk out it runs better a 1500 rpm but that sounds crazy. i am getting it set up on thursday on rolling road and rejetted this should help hopefully. thanks for the advice on leaks i will check this out, which pipes are the main ones to check as there are so many and i havnt got my head completely round all the vaccum pipes yet as i am knew to the job.

If you have a d/V fitted start there.
& clean the idle jet, it's the brass jet on the side of the carb, unscrew it, hold the screw part head down & pull it apart, check the tiny hole for blockages, blow through it, check again, if it loooks like it's still blocked a small needle or thin bit of stiff wire.

Idle Speed

I have always set mine (idle speed) by just listening to the engine, when it sounds right you aren't usually that far wrong.  As for air leaks a good trip is to spray wd40 over the suspect pipe while the engine is running.  If the revs increase there is the damaged pipe.  Make sure you keep it away from the turbo and outlets do it from cold.

Renault figures for the idle speed - 650 +/- 50rpm.
Been around these cars for too damn long!

am i right in saying this???

if your car is sitting at 1000rpm for example
then you replace all pipes and sort all t pieces and what not
then turn car back on...

if the car is sitting at 1500rpm does that mean an air leak in one of the pipes was making the car run lower rpm???

sorry for ther relativly daft question but im havin a debate wiv a friend and some extra input wld do some good
