Scratching my head

[Aimnfire]

well guys

hope someone can help

 

yesterday when about to go home from work

i start my car as usual

but this time round

the rpm shoot to 3k

it stay there until i switch off the engine

 

tot the throttle cable stuck or something

 

tried to play with the throttle when the engine is off

 

start again

still the same

 

only after the 4th start

then the rpm drop back as usual

 

anyone knows what's the cause?

 

today start the car looks like normal

Does your car have those engine lights? Can check your manual, suspect could be your idle or throttle sensor faulty.

[Aimnfire]

ok bro

no engine check light comes out

 

so this what i actually did

today i got a hold of t-spanner size 10

so i open up the cover

 

found out that

1 of the sparkplug cable is loose

so i just push it back in

 

could be 1 of the problem

i will monitor it

 

thanks for your reply

[Maersk1]

bro...partly is due to the throttle body which is dirty, if your car still under warranty, then pls seek dealer for assist !

If one spark plug was loose (they call it 3-piston fire), your car will vibrate badly. The rpm problem seems to have nothing to do with it.

 

If you cold start the car, the auto-choke might push up the rpm, so as to warm up the engine. Else, some of the sensors might have konged up already. Get C&C to do a thorough check, please.

alamak

will get it asap

[Aimnfire]

hey thanks for the suggestion

 

yup was thinking sending in the car

It has something to do with the throttle body idling circuit.

The last time, I took it out to clean; I didn't put it back properly, after starting car, the rpm will shoot to redline.

 

Got to make sure that the gasket on the throttle body is properly seated with no air gaps and all the screws are tightened.

 

Any air leak around the throttle body will cause the idling rpm to shoot up.

more likely ur ECU/ sensor problem.. becos everything u start car is in Open throttle mode, meantime, ECU perform diagnostic to ensure system functioning. after the sensor pick up the signal and sent back to ECU, the circuit is closed and engine will run based on sensor.

hey bro...am also driving the same car as yours....Kia / Cerato !

 

been almost coming to a year now...my car so far so good ! (touch wood touch wood)

Had the same problem as yours not too long ago. Was in Marina Square car park when my idling was around 2500rpm.

 

Only could attribute it to a dirty throttle body (am on K&N).. so got out of the car park, went to Esplanade drive and try to rev it away (under 4000rpm).

 

Seconds later, back to normal. So far, the problem did not re-occur.
