Help Daewoo Cielo 1996 Idle Probelm And Cutt Off!

[anyaddress]

hi friends

please i need your help

my car is daewoo cielo 1996 dohc 1.6v

the car was working fine but suddenly the car has a big problem

the idle level is moving between 0.7 and 1.2 alone (when the car is moving or in park) also the car lost its power so when trying to go with car a little upward road its move hardlyy with a voice from exhaust (blablabla voice ) , and also its completely stopped sometimes (cut off)

here what i did:

1- i checked idle speed sensor and its ok (moving upward and downward normally when ignition on and off).

2-i checked the tps sensor and seems ok since when i pull the connector from it when the car is turning on the rpm is moving upwards so the tps is adjusting fine .

3-i changed the spark-plug and spark wires with original one (new).

4-i checked the desperator cover(i mean the part where the 5 spark plug wires is connected,didn't know its name in English changed by a another one i have) also checked the rotating gap inside it and cleaned it

5- i tring to reset ecu by disconnecting negative battery terminal for about 10 min .

6- i make idle speed learning method

 

so please i need your help because all of this didnt solve the problem

is it a problem in the motor ,i have told by freind that this could happen by miss firing order,but is it possible the timing built is shifted from it position and cause that

hanks you

It seems that a sensor is not working properly. What about the IAC that deals with the motor idling? Have you cleaned it yet?

 

Just be patient and other colleagues will assist you better.

I understand from your words that the car has an automatic gear box. Did you check the oil level of it?

Also, if you do idle learn procedures and the problems seems to persist, and you have no check engine light on in dash board, try to check with a scanner the parameters of the engine.
