I was driving on I-35 in central Iowa, set the cruise at 65, turned it off to slow down and later back on again. Right then, the CEL came on, I brought it into the shop today, but they couldn't find anything with their computer. Could my cruise control have been the culprit?

 

if this only happened once, I'd dissmis until it occurs again.

 

ive seen other cars do that b4, sometimes its just a loose wire or something like that, ive gotten it from a loose gascap before
