lol..... missing as in doesn't run flash

Missing ususally happens when accelerating not really when you back off. maybe you have dirty injectors or dirty throttle body that needs cleaning. Also possibly a coil

sounds like a vaccume leak around the booster! more info would be required tho...

The car works fine when ur driving
and it does it on both fuels. (it's Duel fuel)
it just does it when the car in Drive and stopped (not movin)
and sometimes the engine light comes on when it's cold

[greenacc]

and which error code does it give you ?

[Frog201]

how do you find out a error code

and the engine light only stays on for about 1km When car starts first time
of the day after that no light at all

dude , look up the how to section. There's a black ' computer plug just above the pedals under the dash. Get a thick paper clip or thin piece of wire, bend it and stick it in pins 5 and 6 on the top row of the plug counting from left, and turn ignition key to ON. don't start it though, and count the flashes .... HOW TO SECTION dude,

Also you don't need to post the same question twice - your previous post just a few days ago asked the same question:
