The car engine P2600 Code is very useful thing and you need to solve the problem. You should check the choke plate of the car engine and check is it possible to position correctly? Now check the it is still working or not or should be. Is it opened wholly? If not, then you either trade or repair it. If the part of the car engine impairment is quite plain, I suggest you put down your repair machines and tools as well as start looking about for a standby choke plate to circumvent a repeat of this foul episode. When the car engine is ok, you should fix the car engine properly.
