ACCELERATION PROBLEM POINTER 1.8 MOD 96

Very good afternoon. I have a Pointer Mod. 96, 1.8 and I have the following problem. There are times when the car below 2200RPM I can not make it work well and go to the heads, once I exceed those RPM accelerates normally. It changes sensor: butterfly, step by step, it was done cleaning with carburetor repair kit and injector (it is monopunto). I can't find him back. They told me that it could be the Lambda probe, but disconnect to see what happened and keep doing the same. They tell me that it can be ECU too. If they help me, I am infinitious.

Hello, you will see from my point of view, I would start `for extracting the spark plugs verify as the engine verify resistance of the cables that must be between 6000 to 14000 WHO of the shortest to the longest ok

Check if your engine carries EGR and if it closes completely, as a chicken says the high cbles can also make you pull on low turns.

The spark plugs when they go out very black, with Hollin, clean them and continue with the same and the cables are adequate, I no longer know what else to do hahaha except to sell it hahaha

You already did the whole problem you can be in the fuel pump there is one of the hoses that must be cracked because the defect you make is as if you lack fuel and more than sure it is sure that it is hard for you to start good I wait for your answer
