Idle speed too high

Archives Known Problems
1

I’ve had an intermittent problem with the idle speed during normal running. When on a drive, the revs sometimes sticks to 3000 revs.Only a brief dose of blipping the throttle seems to clear it, but not always!!! Gone back to dealers 4 further investigation. Anyone else with these problems.

Mine does it every now and then… but not very often.

Anyone else with these problems. Is this on an Elise? If so it’s is a well known problem. Mine does it occasionally - it’s quite embarrassing when it happens at traffic lights and the XR3 that pulls up beside you thinks you’re doing it on purpose for a race away from the lights.AFAIK it’s to do with the plastic/metal spring mechanism on the throttle body getting a but rusty or under lubricated so that the spring doesn’t fully close the throttle when you take your foot off the accelerator pedal. If it’s still under warranty you can probably get it replaced. Dealers know about this issue its a case of TADTS cos it sits right under the grill in the engine cover so can get rained on easily. I’ve heard that the part has been replaced/redesigned in the MkII so maybe you can ask to get the new part fitted under warranty.Hope that helpsmatt

Just seen this on the OLC site posted by Nick Adams in response to poor idling problems:“Hello All, interesting one this… The manual could be witten a little more clearly, but what it says is correct as is Simon D. The correct starting procedure is to switch the ignition on, with your foot off the throttle pedal. The system will initialise for approx 2 seconds, when all the clicking and whirring stops you should then apply about 1/4 throttle and crank the engine to start. This allows the Throttle Position Sensor to determine the zero position before the throttle is opened to start the engine. Failure to allow this to happen will mean the TPS will struggle to decide when the throttles are closed, making the idle fuelling and spark less than optimum.Try this and let me know how you all get on…Cheers, Nick”

Don’t know about you guys… but I always start mine without any throttle at all!

7

Me too. Clutch down, no throttle, turn key…

8

And me, no throttle. Wonder why Lotus say you should?

hm… Initializing process befor ignition (whirring and clicking): no clutch, no throttle (just searching for seatbelts). Ignition: clutch down, quarter throttle. Worked out perfectly for me. Without an opened throttle my engine cranks eternally before starting. With quarter-throttle it jumps to life after 3 or 4 seconds.

Bizarre, my Exige has always burst into life on the first or second revolution of the engine (clutch down, no throttle) and it doesn’t get used that much (eh Steve…)

Guys, I am a bit of a novice when it comes to Exige starting (on 650 miles to date), but I have owned Rover cars for the last 10 years and to date I have never depressed any of the pedals prior to starting.This is a practice I have maintained with starting the Exige, so far its not failed.Am I missing something?.

Evey injection car I have ever owned said not to press the throttle pedal when starting, but the Exige manual does say to press the throttle during cranking. My Exige start equally well with the pedal pressed or not [image]http://www.exiges.com/ubb/NonCGI/images/icons/confused.gif[/image]Pressing the clutch pedal is a good idea, because it takes the load of the gearbox off the starter motor.

David - TT have asked me to write the revised start up instructions for your “new” car…I was thinking of adding 2 pre-stages.1. Remove plugs and check for cobwebs;2. Place a teaspoon of oil in each cylinder and with the car in gear and the plugs off roll the car forwards and backwards.

When starting mine now, it makes a loud screeching sound for about 6-7 seconds. It sounds like the alternator belt is slipping… Anyone else have this? (Or could it be the aircon crap???)

Anyone else with these problems. Just had the throttle bodies replaced cause of exactly the same problem - worst when hot. Completed under warrantyMike
