I have a bit of a tricky repair question on a 1988 Honda Accord LX 199,000 Miles, SOHC 2.0 L, Carb, A/T, A20A1 engine (type KG configuration), has had new rebuilt carb fully adjusted, cap, rotor, wires, distributor OK, new fuel filters, fuelpump OK, some vacuum hoses replaced/checked, EGR OK, Anti-afterburn valve OK, engine all good.
The problem is it is sometimes hesitant to start when the engine is cold, and when it is first warmed up it may stall and idle rough and idle fluctates. When it's good and warmed up it seems to be better but still idles rough. I was told it has a very slight Intake manifold leak which goes away when it warms up. Is that really enough to cause this problem? (Tighten Bolts on manifold?) Or should I lean more towards the vacuum control box?(In it is the cranking leak solenoid valve among others). Looking at the diagram for the control box it has vacuum lines from the intake manifold.
What do you guys think?
have the same problem?
