light checking is on also it says check engine cruise

Exact situation with 2005 sport, plus irratic idle started after disconnecting battery for cleaning terminals. Tech explained it completely. There is a memory for the idle and over time (117,000 miles the fuel valve gets dirty and gummy. Without having the memory, the idle tries to find a new idle home but with residue is enough of a problem to give check engine lite and cruise control did not function. They cleaned the intake and valve (bout 1 hour labor) and now problem is completely gone with better response and mileage
