Hi I have a 1988 Delta 88 3.8L v6. It runs super rough at idle and shakes quite a bit. When accelerating it runs fine and on the highway too smooth, as soon as you stop the car at a red light it idles super rough. I tested spark on all cylinders and all good. All the plugs looked good too. I have done an injector flush and cleaned the MAF sensor neither made any difference. Car also has a newer O2 sensor. I'm stuck please help.
