Engine misses at startup until engine warms

When engine gets cold after sitting a few hrs. it misses very bad when you first start it up until the engine gets warm. Will blow a lot of smoke out the exhaust just before it starts to run smooth. After that it runs good all day. 2003 F250 super duty with 6.0 diesel engine. problem started after a replacement key was used by my wife that was made at a local hardware store and not the dealer. Replacement key has no chip in it.

Engine knocking at startup


bad air/fuel mixture could cause rod knock like that, which is a for of backlash or whip like action. Detonation, like very poor grade of fuel. IF your engineis running really rich, the extra rich fuel goes by your piston rings and thins out your engine oil. If you have a bad ROD bearing, it is probably TOO LATE. CLEAN YOUR THROTTLE BODY and IAC valve, since these things fine tune your FUEL/AIR mixture and PREVENT rich running. GOOD LUCK!!

Cold starts ok warms up shakes and stalls


check engine coolant temperature when it gets warmer, or at operating temperature, and verify that the temperature gauge is showing warmed up to operating temperature. If the coolant temperature sensor tells the computer the engine is cold it will over fuel and miss and the engine will die. When cooled down it will run fine until it warms up. Also could be coil if it starts missing after warmed up.

Heap of white smoke on startup but not always


White smoke usually occurs when there is not enough heat to burn the fuel. The unburned fuel particles go out the tailpipe and typically produce a rich fuel smell. It's not unusual to see white smoke in the exhaust during cold weather until the engine warms up.

Faulty glow plugs or control module can cause white smoke on engine start up.

Low engine cranking speed may also produce white smoke.

If white smoke is still visible after the engine has warmed up, the engine may have one or more bad injectors, retarded injection timing or a worn injection pump.

Low compression or air in the fuel system can also be a source of white smoke.

Engine will not idle and run when starting in cold weather


Have a mechanic take a look at your throttle position sensor and engine idle sensor. Make him manually adjust them as opposed to just putting in new ones. It may require that you have to have a higher idle than normal. Your underlying cause is going to be that I am sure you have a lot of miles on your engine.
