    Anyone heard of the ECU giving a false reading on the check engine light. I keep on the code for a vaccum line leak( same one as the recall). It has been checked and repaired twice by the dealer, but the light keep on coming on and will go off on its own sometimes. The dealer says that the ECU is misreading a fault that does not exist. Anyone else had the same problem? I have had all related systems checked and they are within normal parameters.
