Car cough's and chugs when coming to a stop

Why is it that my car runs great while first starting and driving down the road but when I slow down and come to a read light I have to put the car in neutral and rev the motor in order to keep the engine running. I put the car in drive after the light turns green and runs great. Until I slow down again.

This is a common problem w/the Espanza Suza automobile. What model Suza do you have? And have you tightened up the muffler wedge?

Are you using a lockup converter in the 700R4?

Vacuum leak? Flooding Carb? Idle set too low? Timing off?

Yes, That is possible that it might not be disengaging?

Yes, Could be all three. I hope not but I guess I just need to start to check. I have power brakes
that can be possible that the diaframe might be leaking.

The idle mixture set way too lean will act exactly like this. Try backing the mixture screws out two or three turns, make a big enough change that something will happen whether right or wrong. See what happens and go from there.

Choughs and chugs

Thanks alot for your replies I went out to the garage this morning and turned the Idle up a little and opened the mixture screws a little and made all the difference in the world. I began to notice a difference when I changed out the fuel filter Wednesday. The old one I took out I couldn't have the gas drain out of it I had to blow into the line in order to get the gas out. Than I still had trouble getting it clear. Got my new one and there was no air resistance what so ever. So I figured it was a clogged fuel filter since the tank is 55 yrs. old. Didn't notice that much rust in it but I guess there was. New filter, idle turned up, mixtures opened a little made all the difference in the world.I was beginning to think it was bad valves or ring problems. Took compression test yesterday 122 lbs. all cylinders. Runs lot better thanks for your help. Still need to change out rear end. 336 still not right with a 700r4 tranny. Like to get 411's. thanks for all your help. Nick
