Yes my car run okay.... but problem only when i'm in 1st gear

I explain (hard but i will try)

When I start from the 1st, or when i'm in 2nd, sometime like 1 of 10, it's like the motor get no power like a fraction of second... remember it's LIKE... not for real.

Other way to explain, it's like when you release the clutch dramaticly fast when at the 1st gear AND NOT give some gas... when you are at a STOP sign, you are in 1st gear, release the brake and the clutch but not pressing the gas pedal, your car will stall.

it's a "simulation" to give you approx what I get... otherwise, the 9 or 10 my car run good.

And when I start my car, the RPM go high, but normaly after 1/2 sec the rpm go down to normal, like 900rpm idle.

But most of time, with my "check engine" light on, the RPM don't drop to 900 (approx, because I don't have a rpm, but sound like) and keep to 1500-1700 for 3 or 4 seconds... and that only 2 or 3 times in a row (start the car, RPM HIGH... go to R, back-up to exit my parking place, after I press the clutch, RPM go high again, and NEVER go high again @ IDLE until my NEXT engine start)

For my code, I've got 2 sequences of code

The first i've got 111, that mean all system is ok between the computer and the code reader

After that, I got BIP BIP BIP BIP BIP PAUSE BIP BIP BIP BIP BIP BIP BIP = 57

Nothing else.

i've repeat the procedure twice, alway's the same result.
