Black Smoke on Start up. Inconsistent missing.
Need to Pick peoples brains with this one. Here is the story. Spent lots of dollars on my ea. Probably wasted. But here goes anyway. Head was replaced recoed, Injectors, oxygen sensor, Fuel pump, Temp Sensor, New Leads, Plugs, Distributor Cap, Rotor and idle speed solenoid.
On Startup every morning the damn thing blows black smoke. Not Blue just black. Obviously running to rich. Once the smoke clears after apx 10 seconds idle increases. Coool. But the damn engine has an inconsistent miss during idle. Its a pain. Car is dual fuel. Miss still occurs on Gas as well. Car makes good power so i dont think its down on compression etc. Any advice is welcome. Can't afford to spend too much Dollars on this old beast. Its cost a small fortune as it is. No codes on the computer according to my mechanics diagnostic machine. Got us both stumpted. HELP.
