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.
i used to have that problem in my car ages ago when the injectors were leaky, you'll find that black smoke is fuel, oil is white i think i heard em say, when i had the problem the fuel would leak from the injectors, then after starting it would puff about of smoke and take 5-6 seconds to get to normal idle, maybe your injectors could be stuffed again who knows, when you do this next time, turn it on and see if it puffs, but then turn it off and start it say 10 seconds later and if it doesnt puff and idle funny it would be something to be with the EFI
Changed Temp Sensor and Thermostat. No change. Funny thing is even running on gas still get inconsistent miss. But the car still pulls quite ok. I just hate it when your in traffic and the damn motor shakes.
