LS 8-cyl

Throttle body failure on 2004 Lincoln Ls (V8). Engine cuts out intermittently and goes to "etc engine failsafe mode", reducing maximum engine speeds to 10-15 miles per hour. Occasional stalls at full speed have also occurred, twice during turns at intersections. Replacement is necessary per Ford / Lincoln dealer.

Vehicle runs very rough. Will not accelerate over 2800 RPM and shakes badly. Check engine light is flashing. Checked codes P0304 and P0306. Chop states it is faulty ignition coils.

2004 Lincoln Ls V8 throttle body failures result in reduced RPM until the car is restarted. On occasion car will stall. Safety issue especially on the high way. Internet search shows known problem with 2003-2004 throttle position sensor. Search also results in vehicles 2003-2006 exhibit this failure. Dealer trying to procure new throttle body but on national backorder...only one company in us fabricates. Approximately $900 part per dealer (contact info available upon request). This is a Ford design problem.
