Question about 2007 Ford E-150 XLT Wagon
A mechanical gov can use springs or fly weights to control the amount of fuel delivered at a given rpm. an electronic does basically the same thing but with the use of speed sencers and cervos that can control fuel, spark, and timeing. the first is a straight forward approach and has worked well over the years. but the secound is more precise and adjustable withe the stroke of a key board. as to which is better, that depends on the application. mechanical works off engine rpms and takes abuse well but can only regulate speed useing rpms so if you have more gears the faster you can go. where as the electronic uses speed sencors that pull info from the trans or wheels and will only let you do the speed set by the computer

following are the general instructions on the start of diagnosing any
electronically controlled engine or transmission problem.
The Engine and Automatic Transmission (not applicable to manual transmissions) in this vehicles drive train are fully electronically controlled by a computer called the PCM and TCM (Power Train Control Module, Transmission Control Module). When a problem like this or other drive-ability related problems occurs the computer stores a record of the problem (there are of course some exceptions to this, like the fuel pump, engine coolant temperature sensor and MAF sensor for instance) in the form of a fault code in its memory, to read these fault codes you must have the systems memory scanned with a special tool. Once the fault code(s) are read you then must perform the appropriate diagnostic testing to find and resolve the problem(s) DO NOT REPLACE ANY PARTS UNTIL A TRAINED TECHNICAIN HAS DIAGNOSED THE PROBLEM TO AVOID SPENDING YOUR HARD EARNED MONEY ON PARTS THAT MAY NOT CORRECT THE PROBLEM. Also always check fuel pressure for correct spec for your make and engine type. Also engine mechanical problems ca cause many drive-ability related problem such as rough idle and other symptoms
