Peugeot 406 traction and idling problem

Hello everyone, first of all I'm new to the forum. My tool is 2000 model 406 sv. While we were buying, we had the wrath of the master we showed. It turns out that the vehicle was very troublesome. I had to spend 10000 TL because I could not find anyone that I could sell. Anyway, I made the tool usable, somehow 2 problems remained now. The first is that when I first started it, it stopped idle and stopped in gas (I do not run it outside of lpg because it is not reliable at all). The second and more important problem is that when the vehicle is traveling over 50 km, it is born backwards, pulling or slowing down, as if someone pulls the car back and prevents it from accelerating. Like a mehter team, like 2 forward 1 backward. The gearbox has changed completely recently, I think it is because of it. I do not want to sell in the current period, I cannot buy a new one if I sell it, I have already made it at a cost of 10000 TL. I would be very happy if anyone has an opinion. Hi everyone again.

I also have a problem of idling. I changed the idle motor, it was a bit good, but generally, this problem occurs in 406s with LPG. But according to your expression, the idle fluctuation in gasoline may be due to the coil. You should consult a trusted master have the coil tested. And there is still a retraction problem that I could not solve, I guess it has nothing to do with the transmission. I do not change the coil due to the coil, but my master told me that I should change it. If you solve your problem with withdrawal, I would be glad to share it here.

I also wondered what the cost of 10,000 was

Hello again, all the filters of the car were changed, the solenoid valve was the sensor, the transmission oil was changed, we trusted the master when the car was taken, and we did not know that the engine and gearbox oil leaks and the undercarriage were completely exhausted because the man was not looking at the lift. Changed up to the rear crank seal. Engine oil changed 3 times. When the last car was on the road 3 times, we had to change a zero gearbox for 4500 TL. Recently, we changed all sub-sets and pads. The timing and 4 more tires will change, plus there are the problems I mentioned above. Unfortunately, the former owners of the car did not look at anything. When you look at it from the outside, hey mashallah look at the majesty, but here's the inside burned me. Let me look at this ignition coil and write it here. Greetings from Adana.

Aleyküm Hi :) Well, well, well, if all your problems are solved, you will be relieved. 406s are not models that cause problems all the time.

I wonder if anyone has any other information on the subject?
