I think he already got that replaced. It's a small valve below the throttle body.
My dad's 22 month old esteem is suffering from this problem. MASS says throttle body needs replacement. The car has done only 15K kms till date.

MUL usually use TVS plugs in most of their cars. A switch to better plugs like NGKs will definitely negate any problems if they are indeed related to the spark plug. Like amit has mentioned, he had noticed a difference on switching to NGKs.

Also an interesting thing to note is that manufacturers usually tend to stick to bare minimum specs when it comes to consumables like engine oils, spark plugs and if you do upgrade you will see a significant improvement in performance.

Guess, a check with a Tech 2 scanner is the only way to sort this out.

hi,
I am having a small trouble with my Ikon 1.3. Since last 4-5 times when I start the car, it starts revving by itself and goes upto 1500rpm when in motion without the accelerator being pressed have to control it by braking but then it gets normal after some running. I am wondering what is the reason?
Is it because I am starting the enging after 4-5 days.The car generally comes out only during the weekends?

it happens on every car when the engine is started in cold condition. its the auto choke because of which extra fuel is pumped in the engine during cold start. this is to protect the engine by providing lubrication.
its very normal. dont worry. infact its good that everything is functioning properly

Thank you Amit, I was guessing it to be the same that it might be because of the cold start, but did not know of the auto choke thing. thanks a lot. So, I really dont have anything to worry about.

Hi, I experienced a similar problem last night.

The RPM dropped well below normal ( normal being 800 idle) when I turnd the headlights on and the engine turned off automatically.

I drove without the healight and it was fine. Happened, inbetween shifting gears when i eased up on the accelerator. happend twice.

1. Alternator is 5 months old, replaced by A.S.S and they did tell me it comes with a years warranty
2. The battery, bosch super 4 plugs around 4 months old
3. The coil pack, plug wires are 8 months old.

I dont know what caused this. i have not changed or upgraded anything to cause more load. This was with the AC off !

Have ya tried replacing the spark plugs ?

I am going to change the spark plugs and check the wiring by removing after market electrical equipment one by one to see if any of them is causing the problem.

i have put ngk g power platinum tip sparkplugs. after the sparkplug change this reduced to a small extent but not completely gone.

i know one thing. its not due to any another equipment. its solely due to headlights. i have 2 amlifiers, sub and other 12v gadgets. but this has started only after putting the 100-90 bulbs.

Few posts before. It was mentioned that this probelm is due to extra power required by headlights. It is mostly true as headlights starts drawing 200W instead of 120W compared to OEM bulbs. Now this extra power required makes rev higher to get more juice from alternator.

A suggestion would be to higher the idle a little. It might stop the fluctuations.

Also, as the car gets older, A.S.S tend to set the idle higher. Not sure Why?
