U0687 Possible Solution:

Gasoline engines use spark plugs to cause an explosion of fuel within the cylinder. In a properly timed engine, this explosion occurs at the proper moment to send the piston to the bottom of the cylinder and provide power to the drive shaft. If the plug wires are out of sequence, the explosion occurs at the wrong time. The improper timing of the explosion sometimes pushes the cylinder the wrong direction or interferes with the turning of the crank. As a result, the engine stutters or backfires, if it runs at all.

OBD-II Diagnostic Network (U) Trouble Code For Engine	Intake Valve Control Solenoid Circuit Low	Fuel Temperature Sensor B Circuit Range/Performance	Ignition/Distributor Engine Speed Input Circuit Malfunction	Shift/Timing Solenoid Malfunction/ 3-2 Shift Solenoid Circuit Electrical

The poor running symptoms are consistent with a MAP sensor malfunction. In addition, in some cases, a bad MAP sensor will not throw a code. Again, the ELD code likely represents a separate wiring issue.
