1992 Civic Shaking In Idle
Hello all! I'm a newbie and if this subject has been prviously addressed I apologize . I own a 1992 Honda Civic EX with 119,000 miles on functioning odometer. When I stop at a red light it starts to shake (when still in gear DRIVE) but stops shaking when I put it in Neutral. When I accelerate at the green light it drives fine. I've gotten up to 70-90 on the parkway easily.
The speeding ticket I got proves it! LOL
One mechanic I used for the first time says it's only running on three cylinders (after performing a compression test: Reading 150 on cylinders 1,3 and 4 but zero on #2. I don't know him well enough (yet) to trust his diagnosis. Another theory is air intake valve. Before i go to another mechanic foa a 2nd opinion, I thought I's ask here.
car is also emitting white smike from exhause and yes it does burn oil.
Thank you for your feedback.

Since this is a DIY type of forum, here is a test you can do yourself.
Warm up the engine and let it idle in park. Unplug the wires from the fuel injectors one at a time to temporarily shut down each cylinder. (You will need to undo the wire clip around the base of the plug for it to come off.) When you kill a good cylinder the engine will slow down and run rough. If the cylinder is already dead (such as #2 is suspected), nothing will happen when you disconnect its injector.

Or you could do the same operation pulling the spark plugs one at a time.
Compression testers can be gotten pretty cheap at places like harbor freight.

They are pretty easy to use.
Disconnect wires going to the distributor.
Remove spark plug wires from spark plugs. (I typicaly only do the one that I am working on)
Remove the furthest right spark plug (cylinder #1)
Thread the tester in.
Turn the ignition to start and wait for it to cycle a few times.
Make a not of the value on the dial.
Repeat for the other 3 cylinders.
Whole process takes about 20 mins if you don't know what you are doing and probably costs less than that diagnostic you had done.
