[Shop-talk] Honda car question

[John T. Blair]

Shop content: a neighbor came into my shop (garage) and asked me a 
question about his 2004 Honda Accord with about 87,000 mi on it.

When he accelerates above 50 MPH the car vibrates.  He took me for a 
test ride, and it is very previlant.  You feel it through the entire car.

As soon as he quits accelerating the ride smooths out.  As long as he is hold
a constant speed everything if fine.  But if he trys to accelerate 
the vibration starts back up.

The check engine light is **not** on.  The only light that is on is the maint.
required light.

I don't think the problem has anything to do with the plugs, wires, 
injectors, or fuel pump as any of those items should throw a code.

I thought about a wheel ballance problem, but the problem should not go
away when holding a steady speed.  He's also had the tires ballanced to
try and correct the problem to no avail.

My diagnostic skill are starting to dwain, I think.  So I thought I'd come to
the well of knowledge and see if anyone had any idea of where to look or
what to look for.

TIA

John
