Acceleration failure
Renault 19 2000 1800000 miles
Hello, everyone. I have a Renault 19, 1.6, model 2000 and it occasionally happens that, when accelerating slowly, the engine does not respond properly; it accelerates and decelerates continuously as if fuel was not reaching correctly. However, if I accelerate it deeply, there is no failure at all. The check light remains turned on permanently. At idle speed, the car has got a discontinuous power cut. I've already changed: oxygen sensor, distributor cap, wires, spark plugs and the steering wheel sensor. When scanning the vehicle, no failure is indicated. What might be wrong? Rotor? Coil? Could you help me, please?

I have a similar problem and the only thing I have found out is that the carburetor rubber base is cracked. I believe that, when changing it, the failure will disappear.

Buddies, I would like to share how I finally solved the problem. On the opposite side of the axle from the accelerator's butterfly valve, there is a platelet that has got a plug and four screws. It is the TPS sensor. I removed it and cleaned it carefully with alcohol and a cotton swab; a lot of dirt came out of it. I then assembled it back and the failure disappeared. The vehicle is now working perfectly. Thank you very much for your help.
