check eng light
I have a 2000 Accord, 5 speed, 4 c ayl. My check engine light came on and was blinking. So I had it checked and a few misfire codes came back, and egr valve, so I replaced the egr. Still having very low compression and almost stalls when coming to a stop, then barely takes off. I've been told I should just get a new engine, but I'm trying to avoid that...Anyone have any input?...

Low compression can indicate the condition of valves and rings primarily.
If compression is low and introduction of some oil into that cylinder
results in a better reading, worn or broken ring(s) are indicated. If no
change, a valve may be in the process of being burned.
Additionally, low compression can indicate a head gasket problem but
usually this is accompanied by other symptoms such as coolant in the
exhaust, oil in the coolant etc. Many times, low compression will occur
in adjoining cylinders.
If burnt valves,I would consider a used engine,because cheap and available low mileage
import engines make so much more sense.
