First check connections to see if any corrosion . Then use a code reader see what all codes pull up (write down) then clear them out and see what happens .

Would a faulty egr valve on my 02 PT Cruiser 2.2crd cause excessive black smoke and injector knock under full throttle....thanks


black smoke is over fueling and although the turbo appears to spin ok the vale variation actuator may not be operating correctly
there are vanes in the exhaust turbine housing that are altered to increase the exhaust gas flow onto the turbine blades for quicker acceleration and these vanes are operated by a vacuum actuator and rod by a sensor
the vanes are subject to extreme heat and can rust stuck open or the hose gets hard and cracks
s not allowing the vanes to work
I would be concentrating in this area before the EGR valve
run the fault codes as well to get a better idea of the possible fault as some systems only put the light on for extreme conditions in engine and transmission

2006 HYUNDAI Elantra develops heavy black smoke and low pulling power runs 147198kms. Please supply the causes


the cause of the heavy black smoke is un-burnt fuel. is from excessive fuel pressure, faulty injectors,ignition timing out. If it is a turbo operation then the turbo is not producing the correct boost for the fuel settings . Check turbo for vane actuation . low power comes from overfuelling, low air flow. run the fault codes to see which sensors are out of parameter.

What fault code is 1664 on a c220 cdi 2003


Fault code P1664 is the Electric Heater Open current and stored.It is a most common fault on these models. If you will try to find it is in the engine compartment by the engine block above the starter motor. As I remember are not repairable and you have to change it. I personally suggest ask a qualified technician to do the job for you.Ask and how much is the cost.
