Honda Repair: 90 Honda Accord, honda accord lx, hesitation problem

Question
My 90 Honda Accord LX has a "hesitation" problem only after gets up to operating temperature(approx 10 minutes after startup).  It feels like when a distributor cap gets wet and you give it gas and the engines kind of misfires. I had replaced the Dist Cap, rotor , wires, and plugs before I realized this only happened after it gets up to temperature. When the car is cold, it runs perfectly, no hesitation at all. There must be some component that is affected afte the car warms up...any ideas?

Answer
Frank,

Check my previous questions. I have answered this question before.
The problem occurs at 1800 rpm correct? Only when warm.
The problem is your EGR ports in the intake manifold are clogged. They need to be drilled out and cleaned. Once you do that, your car will run like new again.
