Did it drop as the engine warmed up? That's normal. Did it drop when you slowed the engine down from a fast idle to a normal idle after it warmed up? That's normal. Did it suddenly drop a whole lot while the engine continued at the same speed? That's not normal. Are you using a mechanical pressure gauge, or the electric idiot gauge in the dash? |
