Hi guys. I have a 92 buick century 3.3 l. The wires, plugs, O2 sensor are new. The check engine light is on. I checked the code and its code 42. That is the by pass or electric spark testing curcuit. The circuit consists of the ecm, crank sensor, cam sensor, and I think that is it. If anyone could help me and point me in the right direction to figuire out how to find out what exactly is causing the problem. The car idles good with a slight vibration but as soon as you put it in drive it drops about 500 rpm and starts running ruff. It almost stalls. The car has sat for a year and a half. I just purched it. I have changed all the fluids, brakes and brake lines, fuel sending unit and battery. All I need to do now is get it safetyed after I fix this problem so any ideas or help will be greatly appreciated. Thanx Aaron
