I owned Acura TL 2008 new. Currently, it has 51300 miles and the check engine on. Brought to dealer (Open road acura on route 18 East Brunswick, NJ) they found codes:P0701 and P0704, cleared codes. After 24 h, the light is on again. I bought an OBD device checked with codes: P0300, P0301, P0304, P0306, P0701 and P0704. How could the dealer tech. missed these codes? The car have been at dealer since Nov. 10, 2010 and now Nov. 22, 2010. The car have not been fixed. Dealer told me they contacted Acura tech. but no solution. Acura tech couldn’t solved their on creation?
