While driving check engine light came on. Vehicle was then taken to a dealership, who performed a diagnostic test that indicated that the intake manifold upper and lower gaskets needed to be replaced. The parts were replaced, but the failure recurred 13000 miles later. The vehicle was then taken to a mechanic, who also performed a diagnostic test in which the failure codes were 171 and 174. The mechanic changed 4 02 sensors, and did a tune up. Also, mechanic a contacted dealership on this issue, who sent them a fax stating if these codes appeared it was a malfunction of the mil lamp, and didn't change the O2 sensors because this wasn't what was causing the problem. They should go to the vacuum light on the intake manifold, and if the fuel pressure on the manifold was lose due to oil contamination then the vacuum line should be replaced, and a new designed LH service cover should be installed or there could be a leak in the intake manifold. Vehicle was then taken back to the dealership, and a diagnostic test was performed again, in which the failure code indicated a leak in the intake manifold.
