engine starts easily, runs very rough, shuts off, only way to keep running is to play with accelerator and try to keep idle over 1200 rpm. engine check lite comes on immediately sometimes, other times after 3 or 4 miles. black condensation comes out of tailpipe only when you start car when cold. no smoke. Runs fine on hwy. will idle fine most of the time. Once in a while at stoplight idle drops off and engine shuts down.Changed IAC valve with new one. no real change. car has 99000 miles, new plugs, no visible loose hoses or wires.... Thanks for your help.....
