Hi guys. I have a Buick Park Avenue Bj 1993, 173hp. He drives wonderful, doesn’t need a lot of fuel and is in a tip-top condition. But he has a big Macke. If the engine is warm and has been turned off for a few minutes and you want to start it again, the engine makes like an “old tractor”, bangs, pats, shakes and does not take on gas. If you have played some times with the accelerator, whether tender or brutal, he calms down again and then runs again as if The game then repeats itself, in the same way, when you make a warm start again. If the car is cold, it starts as if there was nothing else. In the meantime, pretty much everything that you can change was changed. Ignition module, ignition coils, ignition cable, crankshaft sensor, camshaft sensor, Lambda probe, poti on the air volume meter, gasoline filter and the engine control unit and then also the EE-PROM, which is in the control unit, the injection nozzles were cleaned and the actuators all have uniform resistance values. But unfortunately NO success. Now all the people around the car are standing around and have smoking heads, because nobody knows where to look. Now I am looking for someone who has the golden idea what that could be. The vehicle is sold and the customer should get a car with which he can drive without restrictions.
