Hi,

I have an '87 Accord DX with carb fuel. My problem is rough running and
lack of power after the engine warms and drops to normal idle RPM (about 700
rpm). It has poor power getting under way or climbing hills from this
point. The problem appears to be intermittant as well. When I remove the
vacuum hose from the EGR valve, the car runs and idles normally. I replaced
the EGR ($200!) and it didn't solve the problem. My manual says that the
EGR control valve A and B could be causing the EGR valve to operate when it
shouldn't. I have not been able to find these and guess they are in the ECU
on the firewall. Is this correct? I took the lid off and looked inside
the box and it looked pretty scary. Has anyone had a similar problem and
is there a drawing (or picture) of the A and B EGR control valves available?
I'm planning to go to a wrecker this weekend to see if I can find a used
box. Could a bad oxygen sensor cause this problem?

Thanks in advance.
