Where are you from? Try to visit Motor Doctor in Phoenix Petroleum, Marcos Hiway. They have computerized engine diagnostics and should be able to pinpoint your problem accurately. You will save a lot of time and money in the process. Most mechanics kasi ala-chamba. Don't be overwhelmed by the euro cars in the shop though. I'm also an APV owner.
