hello

when I stop at a red light or a stop
the engine gives a shot as if he wanted to stop
only when the rpm is under 500. but the engine does not stop
just like a hiccups

But it does not do it all the time
the problem is difficult to reproduce

there is no alarm.

is this someone already had this problem

 

Either the IAC, TPS or a dirty throttle body.

 

Thanks JKAETON you for your response ultra-quick

I have this problem since exactly 9 months after a change of spark plug
and of the ignition coil.

is what the change of these two parts may have a link with my problem

thanks

 

Is your check engine light on or have you had the vehicle scanned for stored codes?

 

Yes it has been scanned
No Error No Code

nothing

 

I would also inspect your plugs and coils. Check for vacuum leaks.

 

yes there was error code
just before they change the spark plug
the Automobile was no longer advancing.

they have to change the spark plug (6)
and the ignition coil and also fuse

and since that time
I have problems like hiccups under 500 rpm

thanks

 

the mechanics have to change these two pieces
tps and IAC and the problem is still there
.

do you have any other solution to suggest me
