Question about 2001 Ford Focus
Hi I have a Ford Focus 2001(Y) 1.6 and am having problems with the car jerking under acceleration. There are no problems when the car is idling or revved when stationary. When the problem occurs and the car goes jerky the radio is also effected and sometime the door warning light will come on then go off after a while. I have read some posts about the mass air flow sensor and problems with acceleration but this seams to be effecting electrical areas of the car as well. I am also hgaving trouble finding the MAF sensor as the layout seems to differ form the 1.8 model i have seen pictures in the haynes manual I have.
Any help would be greatly welcome.
Check the battery ground wire for tight and clean on the engine
check both battery terminals are clean and tight
the problem is from a loose /broken wire that is moving when the engine reacts to load ( engine mount failure )
on some other makes it can be traced to the cam position or crank position wires broken or bare

SOURCE: 2001 Ford Focus radio code
Sometimes, the radio code is label, in back side of the radio; you need take off the radio for check it. Other times this code is in the last page from owners manual.
If you can't find it, maybe need call to the Ford dealer with your VIN number and they send to you (sometimes need pay for this service).

Black smoke indicates you are running rich. You may have to address the fuel injectors to make sure one is not stuck open. After replacing the MAF censor this would be my next step. Also your turbo seal might be leaking causing your truck to run rich throwing off the o2 censor. Also you can get black smoke from turbo blowby. Not burning oil but actual oil passing the rear turbine seal and getting into the exhaust. This should give you a few good places to check out. Good luck to you.
