I have a 96 buick skylark with the 3100 v6 in it. I recently blew the lower intake gasket, and had to replace it. Since I put the car back togethor it idles very rough. It seems like it is missing at idle, but all plugs have spark. The exhaust smells like gas which tells me that it is running very rich. I tried to hook my engine scanner up to the port, but the port appears to not be working. I have replaced with new parts the following sensors and components; ECM, EGR valve, coolant temperature sensor, idle air control valve, and fuel pressure regulator. None of those components seemed to make a difference. Is there anyway to read the engine codes manually, and what do I need to look for to fix the idle problems. Also the motor does not knock or have a stuck valve ticking.
have the same problem?
