Auto Choke

[ajwad]

Hi guys,

I am facing a problem. i am using a Mazda 323 2000 1.6v auto.

I cleaned the air flow sensor and the throttle body by only removing the hose. i used simoniz carb cleaner for this. after i started the car i notice that the auto choke is not happening and the rpm drops to zero and the engine vibrates and stops. but on the run there is no problem.

what do you think has happened. pls help

auto choke on an EFI?

My guess is is you may have taken out a vacuum line cleaning the TB. Look for any hose that are loose. Also Simoniz carb cleaner? Isn't that the kind that costs over a thousand a can?

Well it cost me 1500/= odd. Any way i started the car in the morning and it auto choked or raved to 2000rpm and dropped to 1000rpm as usual. But after that it vibrated a little and dropped to zero and the engine stopped.

Is there a throttle sensor or a idle control sensor???? may be when i sprayed the cleaner into the throttle body, it would have got blocked with the carbon which is removed???

On the normal run the car is perfectly OK. Its only during the start this happens.

Well guys today my car is perfectly OK. and its as normal.may be the carbon which was stuck in one of the sensors (Idle control) has gone away.
