Q&A

I own a 1993 toyota corolla LE with approximately 217,000 miles on it. I have recently just changed the oil and filter and replaced the exhaust manifold on the car. A mechanic and family friend of ours replaced the manifold. The loud vibration noise coming from outside and inside the car was suppose to go away after replacing the manifold. Once starting up the car from the outside the noise cannot be heard that much. However when sitting in the driver side I hear a loud noise at times. Mostly when I'm on the highway and when first started up. When the car is started it seems to idle high, which is normal to idle high when it is cold. Once the engine warms up it seems to idle ok but sometimes still idles over the 1000 rpms. Now I don't know if the noise is just something that is with this older car seeing how it has high miles or if something else is wrong. Please help.
